<p>A problem arises when building R interfaces to C/C++ libraries involves testing: how to go about replicating the existing C/C++ tests in R without undue effort. If the C/C++ tests are simple and small enough, they can be manually translated. However, when there are many tests, and each test initializes its own large data structures, the task becomes a chore.</p>
<p>We faced this problem with a recent release of the <a href="https://cran.r-project.org/package=ECOSolveR"><code>ECOSolveR</code></a>, a solver package crucial to our larger package <a href="https://cvxr.rbind.io"><code>CVXR</code></a>. Until version 0.4, we had been content with including one small test and a larger one using saved <code>RDA</code> files in the R package. But with our work on <code>CVXR</code> moving towards a version 1.0 release, we wanted to batten down the hatch.</p>
<p>The <a href="https://github.com/embotech/ecos"><code>ECOS</code></a> C library has about 28 tests and many of them include large, initialized arrays as test data. For example, see <a href="https://raw.githubusercontent.com/embotech/ecos/2954b2a640f2194bf91dbf51e682be17012d7698/test/MPC/MPC01.h">this</a>.</p>
<p>The initial thought was to parse out the arrays in the C source and write out R equivalents for testing. But that could be error-prone and if a test failed, we could never really be sure that our translation was not a problem.</p>
<p>So we looked around for a <a href="http://threevirtues.com/">lazy</a> solution that would let us create R data structures from within the C test code.</p>
<div id="enter-rinside" class="section level2">
<h2>Enter <code>RInside</code></h2>
<p><a href="http://dirk.eddelbuettel.com/code/rinside.html">RInside</a> allows one to embed R inside C/C++.</p>
<p>To use <code>RInside</code>, one initializes a handle to the R process in the C/C++ program. This handle can be used to assign R variables to values held in C/C++ scalars, arrays, etc. One can also evaluate arbitrary strings using the R process, which is quite handy: we can use it to execute a <code>saveRDS</code> call to save R structures in a file. The C++ snippet below shows a simple example. (To run the example, first untar the <a href="https://cran.r-project.org.package=RInside">RInside</a> source, copy <code>test.cpp</code> below to the <code>RInside/inst/examples/standard</code>, and <code>make test</code>.)</p>
<pre class="c"><code>// test.cpp
#include <RInside.h>
// Stuff a double array in a std::vector
std::vector< double > dVec(double *data, int len) {
std::vector< double > result;
for (int i = 0; i < len; i++) result.push_back(data[i]);
return(result);
}
#define DLEN(x) x? (int) (sizeof(x) / sizeof(double)) : 0
int main(int argc, char* argv[]) {
int n = 1;
double y[] = {1.0, 2.0, 3.0};
RInside R(argc, argv);
R.assign(n, "n"); // assign R variable n to C scalar n
R.assign(dVec(y, DLEN(y)), "y"); // assign R variable y to C vector y
std::string rds_file = "out.RDS";
R.assign(rds_file, "rds_file"); // assign R variable rds_file the value "rds_file"
R.parseEvalQ("saveRDS(list(n = n, y = y), file = rds_file)");
return 0;
}</code></pre>
<p>Note the use of some macros to determine lengths of initialized C arrays; in particular, we account for the fact that the array pointer could be <code>NULL</code>, common in the code we encounter. Not shown here is a similar macro that can be used for an initialized integer array. (Dynamically allocated arrays pose no difficulty since the lengths would be known.) Such macros are made accessible to the C/C++ code via included headers.</p>
<p>The following features of the <code>ECOS</code> C tests make it possible to exploit <code>RInside</code>.</p>
<ul>
<li>Each C test is in a single source file. One exception has five tests in a single file.</li>
<li>Each C test has a pattern: a call to a <em>setup</em> function to set up the data, followed by an actual call to the solver.</li>
<li>Most (but not all) arrays are initialized in the C source.</li>
<li>The types of the variables in the setup function call are fixed.</li>
<li>The tests are all invoked from a single test harness.</li>
</ul>
<p>This suggests a following strategy.</p>
<ol style="list-style-type: decimal">
<li>Create an R process in the C library testing harness.</li>
<li>Modify each C test source file by inserting <code>RInside</code> calls <em>before</em> calling the setup function. These calls will save the C data in R data structures, and export the R data using a call <code>saveRDS</code>.</li>
<li>Rerun the C library tests to generate the <code>RDS</code> files.</li>
<li>Use the generated <code>RDS</code> files in R package tests.</li>
</ol>

<h2>Example</h2>
<p>Taking <a href="https://raw.githubusercontent.com/embotech/ecos/2954b2a640f2194bf91dbf51e682be17012d7698/test/MPC/MPC01.h">one test</a> as an example, the setup call (near the bottom of the file) has the following form:</p>
<pre class="c"><code>mywork = ECOS_setup(MPC01_n, MPC01_m, MPC01_p, MPC01_l, MPC01_ncones, MPC01_q, 0,
MPC01_Gpr, MPC01_Gjc, MPC01_Gir,
MPC01_Apr, MPC01_Ajc, MPC01_Air,
MPC01_c, MPC01_h, MPC01_b);</code></pre>
<p>And since the signature of <code>ECOS_setup</code> is known, the parameter types (scalars or arrays) can be fixed.</p>
<pre class="r"><code>var_type <- c(n = "int", m = "int", p = "int", l = "int", ncones = "int",
q = "int*", e = "int",
Gpr = "double*", Gjc = "int*", Gir = "int*",
Apr = "double*", Ajc = "int*", Air = "int*",
c = "double*", h = "double*", b = "double*")</code></pre>
<div id="extracting-c-variable-names" class="section level3">
<h3>Extracting C variable names</h3>
<p>A simple string match in R can easily identify the starting and ending lines of the C setup invocation in the test source file and return a list of the C variable names in each call.</p>
<pre class="r"><code>get_setup_vars <- function(source, file_source = TRUE) {
n <- length(lines <- if (file_source) readLines(source) else source)
starts <- grep("ECOS_setup", lines)
potential_ends <- grep("\\);$", lines)
ends <- sapply(starts,
function(i) potential_ends[potential_ends >= i][1])
## starts[i]:ends[i] are chunks of interest.
lapply(seq_along(starts),
function(i) {
lines[starts[i]:ends[i]] %>%
paste(collapse = "") %>%
stringr::str_replace(pattern = "(.*ECOS_setup\\()", replacement = "") %>%
stringr::str_replace(pattern = "(\\);)$", replacement = "") %>%
stringr::str_split(pattern = ",") %>%
magrittr::extract2(1) %>%
stringr::str_trim()
})
}</code></pre>
<p>A test invocation.</p>
<pre class="r"><code>source_lines <- c('mywork = ECOS_setup(MPC01_n, MPC01_m, MPC01_p, MPC01_l, MPC01_ncones, MPC01_q, 0,',

</div>
<div id="inserting-c-code" class="section level3">
<h3>Inserting C code</h3>
<p>The next task is to generate the code to be inserted before the call to setup. The following code does the job, taking the types of each of the variables in the setup call and making use of macros shown in the C++ example above.</p>
<pre class="r"><code>#' Assign a variable in R

gen_cpp <- function(c_name, var_type, rds_file) {
r_name <- names(var_type)
result <- sapply(seq_along(var_type),
function(i) {
if (var_type[i] == "int" || var_type[i] == "double") {
set_val(c_name[i], r_name[i])

set_dvec(c_name[i], r_name[i])
} else {
stop("Unknown variable type")
}
})
## Create list to save:
output <- paste("foo <- list(",
paste(sapply(r_name, function(x) paste(x, "=", x)), collapse=", "),
")")
## Set output file name and insert call to R saveRDS
c(result,

set_val('fname', 'fname'),

}</code></pre>
</div>
<div id="does-it-work" class="section level3">
<h3>Does it work?</h3>
<p>We can check that the appropriate C code is generated for inserting into the file.</p>

<h2>Summary</h2>
<p><code>RInside</code> can be part of the solution for generating R package tests based on underlying C/C++ library tests. The above approach, with some minor modifications, enabled us to reprogram all 28 C tests for our R package. The modified C test source can be found on <a href="https://github.com/bnaras/ecos-2.0.7-rinside/">GitHub</a>. For instance, compare the <a href="https://raw.githubusercontent.com/embotech/ecos/2954b2a640f2194bf91dbf51e682be17012d7698/test/MPC/MPC01.h">original source of one test</a> to the <a href="https://raw.githubusercontent.com/bnaras/ecos-2.0.7-rinside/master/test/MPC/MPC01.h">modified one</a>. The modifications are towards the end.</p>
<p>Once the modifications were inserted into the C source files, the C tests were re-run to generate <code>RDS</code> files now included in <code>ECOSolveR</code> version 0.5. It was then quite straightforward to add the tests using <a href="https://cran.r-project.org/package=testthat"><code>testthat</code></a> as may be seen from the <a href="https://github.com/bnaras/ECOSolveR/blob/master/tests/testthat/test-ecos-src.R">R test source</a>.</p>

How to Avoid Publishing Credentials in Your Code
https://rviews.rstudio.com/2019/03/21/how-to-avoid-publishing-credentials-in-your-code/
Thu, 21 Mar 2019 00:00:00 +0000https://rviews.rstudio.com/2019/03/21/how-to-avoid-publishing-credentials-in-your-code/
<p><em>Roland Stevenson is a data scientist and consultant who may be reached on <a href="https://www.linkedin.com/in/roland-stevenson/">Linkedin</a>.</em></p>
<p>When accessing an API or database in R, it is often necessary to provide credentials such as a login name and password. You may find yourself being prompted with something like this:</p>
<p><img src="/post/2019-03-15-roland_files/roland.png" alt="Figure: Providing credentials via an interactive prompt" /></p>
<p>When writing an R script that requires a user to provide credentials, you will want a way to have the script prompt the user or, better yet, programatically provided the credentials in the R script. Either way, be careful! You don’t want to put your credentials out there in the clear for all the world to see. Best practices<sup class="footnote-ref" id="fnref:3"><a href="#fn:3">1</a></sup> emphatically state:</p>
<blockquote>
<p>As with every programming language, it is important to <strong>avoid publishing code with your credentials in plain text</strong>.</p>
</blockquote>
<p>So, how can we provide credentials without putting them in the script itself? There are a variety of options described in RStudio’s <a href="https://db.rstudio.com/best-practices/managing-credentials/">“Databases using R”</a>.</p>
<p>I will focus on two cases:</p>
<ul>
<li>simply prompting for credentials via <a href="https://cran.r-project.org/package=rstudioapi"><code>rstudioapi</code></a>
<ul>
<li>suitable for simple credential management</li>
</ul></li>
<li>storing sets of encrypted credentials in a local file via the R <a href="https://cran.r-project.org/package=keyring"><code>keyring</code></a> package
<ul>
<li>suitable for more complicated credential management</li>
</ul></li>
</ul>
<h3 id="prompting-for-a-username-and-password">Prompting for a username and password</h3>
<p>If an R Script requires only one set of credentials and those credentials are easy to remember, it may be easiest to prompt the user for them using <code>rstudioapi</code>. A typical example would be prompting users for their username and password to access a corporate database:</p>
<pre><code>username <- rstudioapi::askForPassword("Database username")
password <- rstudioapi::askForPassword("Database password")
</code></pre>
<p>This method may also be convenient if the user’s credentials tend to change over time.</p>
<h3 id="the-r-keyring-package">The R Keyring package</h3>
<p>A more sophisticated option is to use the R <code>keyring</code> package to store and access encrypted credentials locally. This might be more suitable if multiple credentials exist to access a variety of services (think multiple access tokens). With <code>keyring</code>, one password unlocks the keyring which then provides access to all the credentials.</p>
<p>To use the <code>keyring</code> package, a user only needs to to install and load the package<sup class="footnote-ref" id="fnref:2"><a href="#fn:2">2</a></sup> and define three strings: the keyring name, a keyring service, and the username that we want to associate our secret credentials with.</p>
<p>The following example shows how to create a keyring name <code>my_keyring</code>, with credentials to access <code>my_database</code> as <code>my_username</code>. We first create a <code>backend_file</code> type of keyring which will store the encrypted credentials in the user’s home directory ( <code>~/.config/r-keyring</code>). With <code>keyring_create</code>, we prompt for the password that will unlock the keyring. Finally, we store a credential in the keyring with <code>set</code> before locking it with <code>keyring_lock</code>.</p>
<pre><code>library(keyring)
# Set variables to be used in keyring.
kr_name <- "my_keyring"
kr_service <- "my_database"
kr_username <- "my_username"
# Create a keyring and add an entry using the variables above
kb <- keyring::backend_file$new()
# Prompt for the keyring password, used to unlock keyring
kb$keyring_create(kr_name)
# Prompt for the credential to be stored in the keyring
kb$set(kr_service, username=kr_username, keyring=kr_name)
# Lock the keyring
kb$keyring_lock(kr_name)
# The encrypted keyring file is now stored at ~/.config/r-keyring/ and can be
# accessed by any R program that provides the keyring password
</code></pre>
<p>We can store credentials for multiple usernames per service, and multiple services per keyring. This is ideal in the case of an application that must access a variety of services via access tokens. The encrypted credentials file can either be published with the code, or perhaps for extra security, distributed via a separate channel.</p>
<h2 id="retrieving-credentials">Retrieving credentials</h2>
<p>To retrieve credentials, set the same three variables and use the <code>keyring</code> <code>get()</code> function, which will prompt us for the keyring password that we set when we called <code>create</code>. A retrieval script might look like this:</p>
<pre><code>library(keyring)
library(DBI)
# Set variables to be used in keyring.
kr_name <- "my_keyring"
kr_service <- "my_database"
kr_username <- "my_username"
# Output the stored password: normally you would not want to do this
keyring::backend_file$new()$get(service = kr_service,
user = kr_username,
keyring = kr_name)
# Establish connection to Teradata retrieving the password from the keyring.
dbConnect(drv = odbc::odbc(),
dsn = "my_dsn", # set DSN options in ~/.odbc.ini
pwd = keyring::backend_file$new()$get(service = kr_service,
user = kr_username,
keyring = kr_name))
</code></pre>
<p>With this, we are able to retrieve arbitrary credentials for a particular username and service, allowing us to manage much more complicated sets of credentials with a single password.</p>
<p>So, which is the best way to ensure that plain text credentials are not published with code? If your code relies on a limited number of credentials, an interactive prompt may be the more suitable choice: code users know what their username and password are and can easily enter them interactively.</p>
<p>If the code requires multiple, hard-to-remember, or cumbersome to provide credentials, you might want to consider using keyrings. Users will only need to provide one password, which will unlock the keyring and provide access to all credentials.</p>

The reticulate package solves the hardest problem in data science: people
https://rviews.rstudio.com/2019/03/18/the-reticulate-package-solves-the-hardest-problem-in-data-science-people/
Mon, 18 Mar 2019 00:00:00 +0000https://rviews.rstudio.com/2019/03/18/the-reticulate-package-solves-the-hardest-problem-in-data-science-people/
<p><em>Andrew Mangano is the Director of eCommerce Analytics at Albertsons Companies.</em></p>
<p>Part I - Modelling</p>
<p>The <code>reticulate</code> package integrates Python within R and, when used with RStudio 1.2, brings the two languages together like never before. Much more important than the technical details of how it all works is the impact that it has on on both individuals and teams by enabling data scientists who speak different languages to collaborate seamlessly on a project.</p>
<p>A data scientist is first and foremost a problem solver. The ability to frame a problem and decide how it might be solved is what separates someone who merely knows code syntax from someone who is capable of discovering a novel solution to a hard problem. Despite all of the buzz around the field, however, there exists a major skills gap where there is limited talent available.</p>
<p>When I meet someone who shares an analytic mindset and a passion for data science, it is exciting. Unfortunately, when it comes to collaboration, the Python/R language gap among practitioners yields an inefficient separation. Python and R did not easily mix previously. Teams would spend valuable analysis time translating and re-coding, or worse, dividing analysts into groups around one language. I recently heard a recruiter say: “if you program in Python, then you should apply to this team and if you program in R, then you should apply to that team.” How absurd it is to throw the problem solver out of the equation and limit team-building to a language!</p>
<p>In this example, I highlight how the <code>reticulate</code> package might be used for an integrated analysis. While simple, it highlights three different types of models: native R (<code>xgboost</code>), ‘native’ R with Python backend (<code>TensorFlow</code>), and a native Python model (<code>lightgbm</code>) run in-line with R code, in which data is passed seamlessly to and from Python.</p>
<p>In order to provide an open-source reproducible example, we’ll use the <code>BreastCancer</code> data set from the <code>mlbench</code> package. Our task is binary classification to predict the class as ‘benign’ or ‘malignant.’</p>
<pre class="r"><code>library(mlbench) #provides the data set
data("BreastCancer")</code></pre>
<p>Many machine learning models require the data frame to be represented as a numeric matrix. Using <code>sapply()</code>, we convert the data frame to a numeric matrix. To make the example simpler, we remove incomplete observations via complete.cases and remove the Id column. Converting the ‘Class’ column to numeric creates a numeric column as 1 and 2 instead of 0 and 1, which much be corrected.</p>
<p>The matrix is now ready for a 70% / 30% split for training and testing data sets. The initial training and testing sets are in their native dimensions. One of the model frameworks that we plan to use requires scaled data, which is achieved by using the mean and standard deviation in the scale function.</p>
<pre class="r"><code>#convert to numeric for models and remove na values for this example
model_set <- sapply(BreastCancer[complete.cases(BreastCancer),-1], as.numeric)
#format target variable as 0, 1 instead of 1,2
model_set[,10]<-model_set[,10]-1
#Split into test and train sets
indices <- sample(1:nrow(model_set), size = 0.7 * nrow(model_set))
#Target variables
target<-unlist(model_set[indices,10])
test_target<-unlist(model_set[-indices,10])
#create unscaled data set for boosted tree models
unscale_train<-as.matrix(model_set[indices,-10])
unscale_test<-as.matrix(model_set[-indices,-10 ])
#create normalized data set for neural network
mean <- apply(model_set[indices,-10], 2, mean)
std <- apply(model_set[indices,-10], 2, sd)
train <- scale(model_set[indices,-10], center = mean, scale = std)
test <- scale(model_set[-indices,-10], center = mean, scale = std)</code></pre>
<p>Now that we have a training and testing data set, we can train models.</p>
<p>The first model is a native R package, <code>xgboost</code>, short for ‘extreme gradient boosting’. This library can be installed via a simple call of <code>install.packages('xgboost')</code>, and does not require any additional software. The objective function for our classification problem is ‘binary:logistic’, and the evaluation metric is ‘auc’ for ‘area under the curve’ in an ROC framework.</p>
<pre class="r"><code>library(xgboost)
boost_model<-xgboost(data = unscale_train,label=target,booster="gbtree", nfold = 2,nrounds = 25, verbose = FALSE, objective = "binary:logistic", eval_metric = "auc", nthread = 4)</code></pre>
<p>The next model is a “native” R Package, <code>TensorFlow</code> in R using Keras. Keras is a common interface for TensorFlow, which makes it easier to build certain models. Unlike the previous package, there are extra installation steps for this package beyond <code>install.packages('keras')</code>. Once the library is installed, another step is required via <code>install_keras()</code>. TensorFlow in R uses a python backend, which is why additional set up is needed. Despite the underlying technical details about how the code works, most users will likely not even notice because the coding is done entirely in R.</p>
<p>The structure and details of this example model are similar to the MNIST example on the <a href="https://tensorflow.rstudio.com/keras/">RStudio Keras page</a>.</p>
<pre class="r"><code>library(keras)
y_target<-to_categorical(target,2)
tf_nn <- keras_model_sequential() %>%
layer_dense(units = 12,
activation = 'relu',
input_shape = dim(train)[[2]]) %>%
layer_dropout(rate = 0.4) %>%
layer_dense(units = 12,
activation = 'relu')%>%
layer_dropout(rate = 0.3) %>%
layer_dense(units = 2,
activation = 'softmax')
tf_nn %>% compile(
optimizer = optimizer_rmsprop(),
loss = "categorical_crossentropy",
metrics = c("accuracy")
)
history<-tf_nn %>% fit(
x=train,
y=y_target,
epochs = 7,
batch_size = 12
)</code></pre>

<p>The last model to be tested is entirely outside of the R ecosystem. The goal is to take the data we have been using in R, pass it to python, train a model, then pass the results back into R.</p>
<p>As an example, we will use the Python <code>LightGBM</code> package.</p>
<p>To begin, load the reticulate package.</p>
<pre class="r"><code>library(reticulate)</code></pre>
<p>The next code chunk is written entirely in python. RStudio 1.2 allows chunks of python code to be run in the same notebook as R code. Notice that the beginning of the chunk is not <code>{r}</code>, but instead <code>{python}</code>.</p>
<p>Data is passed to Python through <code>r.</code> commands. In this code chunk, the model turning parameters are saved in <code>params</code> and passed in the <code>lgb.train</code> function. The data from R is passed in the <code>r.unscale_train</code>, <code>r.target</code>, <code>r.unscale_test</code>. This is the same data used in the <code>xgboost</code> model.</p>
<pre class="python"><code>import pandas as pd
import lightgbm as lgb
params = {
'boosting_type': 'rf',#or can use 'gbdt',#'dart',
'objective': 'binary',
'metric': {'auc'},

'max_depth': 8,
'feature_fraction': 0.9,

}
lgtrain = lgb.Dataset(r.unscale_train, label=r.target)
model = lgb.train(params, lgtrain, 200)
light_gbm_test = model.predict(r.unscale_test)</code></pre>
<p>(<em>Note that the output has been truncated for publication.</em>) <img src="/post/2019-03-11-mangano_files/man2.png" height = "600" width= 100%></p>
<p>Once the model is trained in Python, it is possible to pass the data back to R using the <code>py$</code> command. In this chunk, which is back in R code, the test set predictions are passed to a data frame in R to compare the performance against the other models.</p>
<pre class="r"><code>lgb_pred<-py$light_gbm_test</code></pre>
<p>This last code chunk creates probability and binary predictions for the <code>xgboost</code> and <code>TensorFlow</code> (neural net) models, and creates a binary prediction for the <code>lightGBM</code> model. Using the binary predictions, we then create basic confusion matrices to compare the model predictions on the test data set.</p>
<pre class="r"><code>xgbpred <- predict (boost_model,unscale_test)

Some R Packages for ROC Curves
https://rviews.rstudio.com/2019/03/01/some-r-packages-for-roc-curves/
Fri, 01 Mar 2019 00:00:00 +0000https://rviews.rstudio.com/2019/03/01/some-r-packages-for-roc-curves/
<p>In a recent <a href="https://rviews.rstudio.com/2019/01/17/roc-curves/">post</a>, I presented some of the theory underlying ROC curves, and outlined the history leading up to their present popularity for characterizing the performance of machine learning models. In this post, I describe how to search CRAN for packages to plot ROC curves, and highlight six useful packages.</p>
<p>Although I began with a few ideas about packages that I wanted to talk about, like <a href="https://cran.r-project.org/package=ROCR">ROCR</a> and <a href="https://cran.r-project.org/package=pROC">pROC</a>, which I have found useful in the past, I decided to use Gábor Csárdi’s relatively new package <a href="https://cran.r-project.org/package=pkgsearch">pkgsearch</a> to search through CRAN and see what’s out there. The <code>package_search()</code> function takes a text string as input and uses basic text mining techniques to search all of CRAN. The algorithm searches through package text fields, and produces a score for each package it finds that is weighted by the number of reverse dependencies and downloads.</p>
<pre class="r"><code>library(tidyverse) # for data manipulation
library(dlstats) # for package download stats
library(pkgsearch) # for searching packages</code></pre>
<p>After some trial and error, I settled on the following query, which includes a number of interesting ROC-related packages.</p>
<pre class="r"><code>rocPkg <- pkg_search(query="ROC",size=200)</code></pre>
<p>Then, I narrowed down the field to 46 packages by filtering out orphaned packages and packages with a score less than 190.</p>
<pre class="r"><code>rocPkgShort <- rocPkg %>%
filter(maintainer_name != "ORPHANED", score > 190) %>%
select(score, package, downloads_last_month) %>%
arrange(desc(downloads_last_month))
head(rocPkgShort)</code></pre>
<pre><code>## # A tibble: 6 x 3
## score package downloads_last_month
## <dbl> <chr> <int>
## 1 690. ROCR 56356
## 2 7938. pROC 39584
## 3 1328. PRROC 9058
## 4 833. sROC 4236
## 5 266. hmeasure 1946
## 6 1021. plotROC 1672</code></pre>
<p>To complete the selection process, I did the hard work of browsing the documentation for the packages to pick out what I thought would be generally useful to most data scientists. The following plot uses Guangchuang Yu’s <code>dlstats</code> package to look at the download history for the six packages I selected to profile.</p>
<pre class="r"><code>library(dlstats)
shortList <- c("pROC","precrec","ROCit", "PRROC","ROCR","plotROC")
downloads <- cran_stats(shortList)
ggplot(downloads, aes(end, downloads, group=package, color=package)) +
geom_line() + geom_point(aes(shape=package)) +
scale_y_continuous(trans = 'log2')</code></pre>

<h3><a href="https://cran.r-project.org/package=ROCR">ROCR</a> - 2005</h3>
<p>ROCR has been around for almost 14 years, and has be a rock-solid workhorse for drawing ROC curves. I particularly like the way the <code>performance()</code> function has you set up calculation of the curve by entering the true positive rate, <code>tpr</code>, and false positive rate, <code>fpr</code>, parameters. Not only is this reassuringly transparent, it shows the flexibility to calculate nearly every performance measure for a <a href="https://en.wikipedia.org/wiki/Binary_classification">binary classifier</a> by entering the appropriate parameter. For example, to produce a precision-recall curve, you would enter <code>prec</code> and <code>rec</code>. Although there is no vignette, the documentation of the package is very good.</p>
<p>The following code sets up and plots the default <code>ROCR</code> ROC curve using a synthetic data set that comes with the package. I will use this same data set throughout this post.</p>

<p>Although not nearly as popular as <code>ROCR</code> and <code>pROC</code>, <code>PRROC</code> seems to be making a bit of a comeback lately. The terminology for the inputs is a bit eclectic, but once you figure that out the <code>roc.curve()</code> function plots a clean ROC curve with minimal fuss. <code>PRROC</code> is really set up to do precision-recall curves as the <a href="https://cran.r-project.org/web/packages/PRROC/vignettes/PRROC.pdf">vignette</a> indicates.</p>

<p><code>plotROC</code> is an excellent choice for drawing ROC curves with <code>ggplot()</code>. My guess is that it appears to enjoy only limited popularity because the documentation uses medical terminology like “disease status” and “markers”.

<p>In this attempt to dig into CRAN and uncover some of the resources R contains for plotting ROC curves and other binary classifier visualizations, I have only scratched the surface. Moreover, I have deliberately ignored the many packages available for specialized applications, such as <a href="https://cran.r-project.org/package=survivalROC">survivalROC</a> for computing time-dependent ROC curves from censored survival data, and <a href="https://cran.r-project.org/web/packages/cvAUC/index.html">cvAUC</a>, which contains functions for evaluating cross-validated AUC measures. Nevertheless, I hope that this little exercise will help you find what you are looking for.</p>

<p>By my count, 157 new packages stuck to CRAN in December. Below are my “Top 40” picks in ten categories: Computational Methods, Data, Finance, Machine Learning, Medicine, Science, Statistics, Time Series, Utilities and Visualization. This is the first time I have used the Medicine category. I am pleased that a few packages that appear to have clinical use made the cut. Also noteworthy in this month’s selection are the inclusion of four packages from the Microsoft Azure team (stuffing 41 packages into the “Top 40”), and some eclectic, but fascinating packages in the Science section.</p>

<h2>Looking Forward in Glaucoma Progression Research</h2>
<p>The contribution of the <code>womblR</code> package and corresponding statistical methodology is a technique for correctly accounting for the complex spatial structure of the visual field. The purpose of this method is to properly model visual field data, so that an effective diagnostic is derived that discriminates progression status. This is one of many important clinical questions that needs to be addressed in glaucoma research. Others include: quantifying visual field variability to create simulations of healthy and progression patients, combining multiple data modalities to obtain a composite diagnostic, and predicting the timing and spatial location of future vision loss. There is opportunity within the glaucoma literature for the development of quantitative methods that answer important clinical questions, are easy to understand, and are simple to use. To this end, in closing this three-part series, we present a final example of a new method that uses change points to assess future vision loss.</p>
</div>
<div id="modeling-changes-on-the-visual-field-using-spatial-change-points" class="section level2">
<h2>Modeling Changes on the Visual Field Using Spatial Change Points</h2>
<p>To motivate the use of change points, we note that patients diagnosed with glaucoma are often monitored for years with slow changes in visual functionality. It is not until disease progression that notable vision loss occurs, and the deterioration is often swift. This disease course inspires a modeling framework that can identify a point of functional change in the course of follow-up, thus change points are employed. This is an appealing modeling framework, because the concept of disease progression becomes intrinsically parameterized into the model, with the change point representing the point of functional change. In this model, the time of the change point triggers a simultaneous change in both the mean and variance process. Furthermore, to account for the typical trend of a long period of monitoring with little change followed by abrupt vision loss, we force the mean and variance to be constant before the change point. For the mean process, and assuming data from a patient with nine visual field tests, this results in <span class="math display">\[\mu_t\left(\mathbf{s}_i\right)=\left\{ \begin{array}{ll}
{\beta}_0\left(\mathbf{s}_i\right) & x_t \leq \theta\left(\mathbf{s}_i\right),\\
{\beta}_0\left(\mathbf{s}_i\right) + {\beta}_1\left(\mathbf{s}_i\right)\left\{x_t-\theta\left(\mathbf{s}_i\right)\right\} & \theta\left(\mathbf{s}_i\right) \leq x_t.\end{array} \right. \quad t = 1,\ldots,9 \quad i = 1,\ldots,52 \]</span> Here, the change point at location <span class="math inline">\(\mathbf{s}_i\)</span> is given by <span class="math inline">\(\theta(\mathbf{s}_i)\)</span>, and <span class="math inline">\(x_t\)</span> is the days from baseline visit for follow-up visit <span class="math inline">\(t\)</span>. A final important detail is that the change points <span class="math inline">\(\theta(\mathbf{s}_i)\)</span> are truncated in the observed follow-up range, <span class="math inline">\((x_1, x_9)\)</span>. In practice, the true change point can occur outside of this region, so we define a latent process, <span class="math inline">\(\eta(\mathbf{s}_i)\)</span>, that defines the true change point, <span class="math inline">\(\theta(\mathbf{s}_i) = \max\{\min\{\eta(\mathbf{s}_i), x_9\}, x_1\}\)</span>. Finally, all of the location-specific effects are modeled using a novel multivariate conditional autoregressive (MCAR) prior that incorporates the anatomy detailed in the <code>womblR</code> method. More details can be found in Berchuck et al. 2018.</p>
<p>We once again rely on MCMC methods for inference, and a package similar to <code>womblR</code> was developed that implements the spatially varying change point model, <code>spCP</code>. This package has much of the same functionality as <code>womblR</code>, and we demonstrate its functionality below.</p>
<p>We begin by loading <code>spCP</code>. All of the visual field data (<code>VFSeries</code>), adjacencies (<code>HFAII_Queen</code>), and anatomical angles (<code>GarwayHeath</code>) are included in the <code>spCP</code> package.</p>
<pre class="r"><code>###Load package
library(spCP)
###Format data
blind_spot <- c(26, 35) # define blind spot
VFSeries <- VFSeries[order(VFSeries$Location), ] # sort by location
VFSeries <- VFSeries[order(VFSeries$Visit), ] # sort by visit
VFSeries <- VFSeries[!VFSeries$Location %in% blind_spot, ] # remove blind spot locations
Y <- VFSeries$DLS # define observed outcome data
Time <- unique(VFSeries$Time) / 365 # years since baseline visit
MaxTime <- max(Time)
###Neighborhood objects
W <- HFAII_Queen[-blind_spot, -blind_spot] # visual field adjacency matrix
M <- dim(W)[1] # number of locations
DM <- GarwayHeath[-blind_spot] # Garway-Heath angles
Nu <- length(Time) # number of visits
###Obtain bounds for spatial parameter (details are in Berchuck et al. 2018)
pdist <- function(x, y) pmin(abs(x - y), (360 - pmax(x, y) + pmin(x, y))) #Dissimilarity metric distance function (i.e., circumference)
DM_Matrix <- matrix(nrow = M, ncol = M)
for (i in 1:M) {
for (j in 1:M) {
DM_Matrix[i, j] <- pdist(DM[i], DM[j])
}
}
BAlpha <- -log(0.5) / min(DM_Matrix[DM_Matrix > 0])
AAlpha <- 0
###Hyperparameters
Hypers <- list(Alpha = list(AAlpha = AAlpha, BAlpha = BAlpha),
Sigma = list(Xi = 6, Psi = diag(5)),
Delta = list(Kappa2 = 1000))
###Starting values
Starting <- list(Sigma = 0.01 * diag(5),
Alpha = mean(c(AAlpha, BAlpha)),
Delta = c(0, 0, 0, 0, 0))
###Metropolis tuning variances
Tuning <- list(Lambda0Vec = rep(1, M),
Lambda1Vec = rep(1, M),
EtaVec = rep(1, M),
Alpha = 1)
###MCMC inputs
MCMC <- list(NBurn = 10000, NSims = 250000, NThin = 25, NPilot = 20)</code></pre>
<p>Once the inputs have been properly formatted, the program can be run.</p>
<pre class="r"><code>###Run MCMC sampler
reg.spCP <- spCP(Y = Y, DM = DM, W = W, Time = Time,
Starting = Starting, Hypers = Hypers, Tuning = Tuning, MCMC = MCMC,
Family = "tobit",
Weights = "continuous",
Distance = "circumference",
Rho = 0.99,
ScaleY = 10,
ScaleDM = 100,
Seed = 54)
## Burn-in progress: |*************************************************|
## Sampler progress: 0%.. 10%.. 20%.. 30%.. 40%.. 50%.. 60%.. 70%.. 80%.. 90%.. 100%.. </code></pre>
<p>To visualize the estimated change points, we can use the <code>PlotCP</code> function from <code>spcP</code>. The function requires the model fit object and the original data set, plus the variable names of the raw DLS, time (in years), and spatial locations.</p>
<pre class="r"><code>VFSeries$TimeYears <- VFSeries$Time / 365
PlotCP(reg.spCP,
VFSeries,
dls = "DLS",
time = "TimeYears",
location = "Location",
cp.line = TRUE,
cp.ci = TRUE)</code></pre>

<p>Using the <code>PlotCP</code> function, we present the posterior means of the change points using a blue vertical line, with dashed 95% credible intervals. Furthermore, the mean process and credible interval are plotted using red lines, and the raw DLS values are given by black points. For this example patient, the majority of the change points are at the edges of follow-up. When the DLS is constant over time, the estimated change points are at the end of follow-up, while any trends that are present before follow-up correspond to the change point occurring at the beginning. This information provides clinicians with visual and quantitative confirmation of functional changes across the visual field.</p>
</div>
<div id="change-points-as-a-proxy-for-progression" class="section level2">
<h2>Change Points as a Proxy for Progression</h2>
<p>To formalize the importance of the change points, we look to convert their presence or absence into a clinical decision. We decide to calculate the probability that a change point has been observed at each location across the visual field. To provide a tool that is useful for clinicians, we create a gif that presents the probability of a change point throughout a patient’s follow-up, and are able to predict one and a half years into the future. In Berchuck et al. 2018, it is shown that these change points are highly predictive of progression.</p>
<p>We begin by extracting and calculating the change point probabilities.</p>
<pre class="r"><code>###Extract change point posterior samples
eta <- reg.spCP$eta
###Convert change points to probabilties of occuring before time t
NFrames <- 50 # number of frames in GIF
GIF_Times <- seq(0, MaxTime + 1.5, length.out = NFrames) # obtain GIF 1.5 years after the end of follow-up
GIF_Days <- round(GIF_Times * 365) # convert to days for use later
CP_Probs <- matrix(nrow = M, ncol = NFrames)
###Obtain probabilties at each time point
for (t in 1:NFrames) {
CP_Probs[, t] <- apply(eta, 2, function(x) mean(x < GIF_Times[t]))
}
colnames(CP_Probs) <- GIF_Times</code></pre>
<p>Now, to create a gif of the probabilities, we use the <code>magick</code> package, and in particular, the functions <code>image_graph</code> and <code>image_animate</code>. Furthermore, we use the <code>PlotSensitivity</code> function from <code>womblR</code> to plot the predicted probabilities on the visual field.</p>
<pre class="r"><code>###Load packages
library(magick) # package for creating GIFs
library(womblR) # loaded for PlotSensitivity
###Create GIF
Img <- image_graph(600, 600, res = 96)
for (f in 1:NFrames) {
p <- womblR::PlotSensitivity(CP_Probs[, f],
legend.lab = expression(paste("Pr[", eta, "(s)] < ", t)),
zlim = c(0, 1),
bins = 250,
legend.round = 2,
border = FALSE,
main = bquote("Days from baseline: t = " ~ .(GIF_Days[f]) ~ " (" ~ t[max] ~ " = " ~ .(Time[Nu] * 365) ~ ")"))
}
dev.off()</code></pre>
<pre><code>## quartz_off_screen
## 2</code></pre>
<p>Now, we animate and print the created gif using the <code>image_animate</code> function, specifying 10 frames per second using the <code>fps</code> option.</p>
<pre class="r"><code>Animation <- image_animate(Img, fps = 10)
Animation</code></pre>
<p><img src="/post/2018-12-12-statistics-in-glaucoma-part-iii_files/figure-html/unnamed-chunk-7-1.gif" style="display: block; margin: auto;" /></p>
<p>This gif has many properties that make it clinically useful. The space-time nature of the image allows for clinicians to understand not only the current state of the disease, but also the progression pattern throughout all of follow-up. Furthermore, the gif shows the pattern and future risk of progression over the next one and a half years, presenting clinicians a tool for planning for future risk.</p>
</div>
<div id="conclusions-and-future-directions" class="section level2">
<h2>Conclusions and Future Directions</h2>
<p>The hope in developing these <code>R</code> packages is for them to be used clinically, and to inspire other quantitative scientists to do the same. When statistical methods are typically developed for medical research, it is more common for the methodologies to be published without any corresponding software package. This means that no matter how impactful the method may be, it is unlikely to make a clinical impact for many years, due to the complexity in implementing the inferential methods. Clinicians are dependent on quantitative methods for analyzing the massive amounts of data that exist in today’s world, and they are typically reliant on the proprietary software that is built into the imaging machines themselves. This software is useful, but because the methods are often not published, it can be difficult to interpret the results. More open-source software being developed for medical research will lead to greater collaboration and visibility of the important problems being addressed by health researchers. The <code>R</code> environment, including CRAN and RStudio, make it particularly easy to create and share <code>R</code> packages, and the development of <code>Rcpp</code> and its relatives allow for the packages to be computationally fast. Our hope is that the <code>womblR</code> and <code>spCP</code> packages illustrate this concept and excite people to get involved in glaucoma research, or one of many other important health areas.</p>

Rsampling Fama French
https://rviews.rstudio.com/2018/12/13/rsampling-fama-french/
Thu, 13 Dec 2018 00:00:00 +0000https://rviews.rstudio.com/2018/12/13/rsampling-fama-french/
<p>Today we will continue our work on Fama French factor models, but more as a vehicle to explore some of the awesome stuff happening in the world of <a href="https://www.tidyverse.org/articles/2018/11/tidymodels-update-nov-18/">tidy models</a>. For new readers who want get familiar with Fama French before diving into this post, see <a href="https://rviews.rstudio.com/2018/04/11/introduction-to-fama-french/">here</a> where we covered importing and wrangling the data, <a href="https://rviews.rstudio.com/2018/05/10/rolling-fama-french/">here</a> where we covered rolling models and visualization, my most recent previous post <a href="https://rviews.rstudio.com/2018/11/19/many-factor-models/">here</a> where we covered managing many models, and if you’re into Shiny, <a href="http://www.reproduciblefinance.com/shiny/fama-french-three-factor/">this flexdashboard</a>.</p>
<p>Our goal today is to explore k-fold cross-validation via the <code>rsample</code> package, and a bit of model evaluation via the <code>yardstick</code> package. We started the model evaluation theme last time when we used <code>tidy()</code>, <code>glance()</code> and <code>augment()</code> from the <code>broom</code> package. In this post, we will use the <code>rmse()</code> function from <code>yardstick</code>, but our main focus will be on the <code>vfold_cv()</code> function from <code>rsample</code>. We are going to explore these tools in the context of linear regression and Fama French, which might seem weird since these tools would typically be employed in the realms of machine learning, classification, and the like. We’ll stay in the world of explanatory models via linear regression world for a few reasons.</p>
<p>First, and this is a personal preference, when getting to know a new package or methodology, I prefer to do so in a context that’s already familiar. I don’t want to learn about <code>rsample</code> whilst also getting to know a new data set and learning the complexities of some crazy machine learning model. Since Fama French is familiar from our previous work, we can focus on the new tools in <code>rsample</code> and <code>yardstick</code>. Second, factor models are important in finance, despite relying on good old linear regression. We won’t regret time spent on factor models, and we might even find creative new ways to deploy or visualize them.</p>
<p>The plan for today is take the same models that we ran in the last post, only this use k-fold cross validation and bootstrapping to try to assess the quality of those models.</p>
<p>For that reason, we’ll be working with the same data as we did previously. I won’t go through the logic again, but in short, we’ll import data for daily prices of five ETFs, convert them to returns (have a look <a href="http://www.reproduciblefinance.com/2017/09/25/asset-prices-to-log-returns/">here</a> for a refresher on that code flow), then import the five Fama French factor data and join it to our five ETF returns data. Here’s the code to make that happen:</p>
<pre class="r"><code>library(tidyverse)
library(broom)
library(tidyquant)
library(timetk)
symbols <- c("SPY", "EFA", "IJS", "EEM", "AGG")
# The prices object will hold our daily price data.

getSymbols(symbols, src = 'yahoo',

map(~Ad(get(.))) %>%
reduce(merge) %>%
`colnames<-`(symbols)

tk_tbl(preserve_index = TRUE, rename_index = "date") %>%
gather(asset, returns, -date) %>%
group_by(asset) %>%

select(-RF)
data_joined_tidy <-
asset_returns_long %>%
left_join(Global_5_Factors, by = "date") %>%
na.omit()</code></pre>
<p>After running that code, we have an object called <code>data_joined_tidy</code>. It holds daily returns for 5 ETFs and the Fama French factors. Here’s a look at the first row for each ETF rows.</p>
<pre class="r"><code>data_joined_tidy %>%

<p>Let’s work with just one ETF for today and use <code>filter(asset == "AGG")</code> to shrink our data down to just that ETF.</p>
<pre class="r"><code>agg_ff_data <-
data_joined_tidy %>%
filter(asset == "AGG")</code></pre>
<p>Okay, we’re going to regress the daily returns of AGG on one factor, then three factors, then five factors, and we want to evaluate how well each model explains AGG’s returns. That means we need a way to test the model. Last time, we looked at the adjusted r-squared values when the model was run on the entirety of AGG returns. Today, we’ll evaluate the model using k-fold cross validation. That’s a pretty jargon-heavy phrase that isn’t part of the typical finance lexicon. Let’s start with the second part, <code>cross-validation</code>. Instead of running our model on the entire data set - all the daily returns of AGG - we’ll run it on just part of the data set, then test the results on the part that we did not use. Those different subsets of our original data are often called the training and the testing sets, though <code>rsample</code> calls them the <code>analysis</code> and <code>assessment</code> sets. We validate the model results by applying them to the <code>assessment</code> data and seeing how the model performed.</p>
<p>The <code>k-fold</code> bit refers to the fact that we’re not just dividing our data into training and testing subsets, we’re actually going to divide it into a bunch of groups, a <code>k</code> number of groups, or a <code>k</code> number of <code>folds</code>. One of those folds will be used as the validation set; the model will be fit on the other <code>k - 1</code> sets, and then tested on the validation set. We’re doing this with a linear model to see how well it explains the data; it’s typically used in machine learning to see how well a model predicts data (we’ll get there in 2019).<a href="#fn1" class="footnoteRef" id="fnref1"><sup>1</sup></a></p>
<p>If you’re like me, it will take a bit of tinkering to really grasp k-fold cross validation, but <code>rsample</code> as a great function for dividing our data into k-folds. If we wish to use five folds (the state of the art seems to be either five or ten folds), we call the <code>vfold_cv()</code> function, pass it our data object <code>agg_ff_data</code>, and set <code>v = 5</code>.</p>

<p>We have an object called <code>cved_ff</code>, with a column called <code>splits</code> and a column called <code>id</code>. Let’s peek at the first split.</p>
<pre class="r"><code>cved_ff$splits[[1]]</code></pre>
<pre><code><1007/252/1259></code></pre>
<p>Three numbers. The first, 1007, is telling us how many observations are in the <code>analysis</code>. Since we have five folds, we should have 80% (or 4/5) of our data in the <code>analysis</code> set. The second number, 252, is telling us how many observations are in the <code>assessment</code>, which is 20% of our original data. The third number, 1259, is the total number of observations in our original data.</p>
<p>Next, we want to apply a model to the <code>analysis</code> set of this k-folded data and test the results on the <code>assessment</code> set. Let’s start with one factor and run a simple linear model, <code>lm(returns ~ MKT)</code>.</p>
<p>We want to run it on <code>analysis(cved_ff$splits[[1]])</code> - the analysis set of out first split.</p>
<pre class="r"><code>ff_model_test <- lm(returns ~ MKT, data = analysis(cved_ff$splits[[1]]))
ff_model_test</code></pre>
<pre><code>
Call:
lm(formula = returns ~ MKT, data = analysis(cved_ff$splits[[1]]))
Coefficients:
(Intercept) MKT
0.0001025 -0.0265516 </code></pre>
<p>Nothing too crazy so far. Now we want to test on our assessment data. The first step is to add that data to the original set. We’ll use <code>augment()</code> for that task, and pass it <code>assessment(cved_ff$splits[[1]])</code></p>
<pre class="r"><code>ff_model_test %>%
augment(newdata = assessment(cved_ff$splits[[1]])) %>%
head() %>%
select(returns, .fitted)</code></pre>
<pre><code> returns .fitted
1 0.0009021065 1.183819e-04
2 0.0011726989 4.934779e-05
3 0.0010815505 1.157267e-04

5 -0.0021715702 -8.341007e-05
6 0.0028159467 3.865527e-04</code></pre>
<p>We just added our fitted values to the <code>assessment</code> data, the subset of the data on which the model was not fit. How well did our model do when compare the fitted values to the data in the held out set?</p>
<p>We can use the <code>rmse()</code> function from <code>yardstick</code> to measure our model. RMSE stands for root mean-squared error. It’s the sum of the squared differences between our fitted values and the actual values in the <code>assessment</code> data. A lower RMSE is better!</p>
<pre class="r"><code>ff_model_test %>%
augment(newdata = assessment(cved_ff$splits[[1]])) %>%
rmse(returns, .fitted)</code></pre>
<pre><code># A tibble: 1 x 3
.metric .estimator .estimate
<chr> <chr> <dbl>
1 rmse standard 0.00208</code></pre>
<p>Now that we’ve done that piece by piece, let’s wrap the whole operation into one function. This function takes one argument, a <code>split</code>, and we’re going to use <code>pull()</code> so we can extract the raw number, instead of the entire <code>tibble</code> result.</p>
<pre class="r"><code>model_one <- function(split) {
split_for_model <- analysis(split)
ff_model <- lm(returns ~ MKT, data = split_for_model)
holdout <- assessment(split)
rmse <- ff_model %>%
augment(newdata = holdout) %>%
rmse(returns, .fitted) %>%
pull(.estimate)
}</code></pre>
<p>Now we pass it our first split.</p>
<pre class="r"><code>model_one(cved_ff$splits[[1]]) %>%
head()</code></pre>
<pre><code>[1] 0.002080324</code></pre>
<p>Now we want to apply that function to each of our five folds that are stored in <code>agg_cved_ff</code>. We do that with a combination of <code>mutate()</code> and <code>map_dbl()</code>. We use <code>map_dbl()</code> instead of <code>map</code> because we are returning a number here and there’s not a good reason to store that number in a list column.</p>
<pre class="r"><code> cved_ff %>%
mutate(rmse = map_dbl(cved_ff$splits, model_one))</code></pre>
<pre><code># 5-fold cross-validation
# A tibble: 5 x 3
splits id rmse
* <list> <chr> <dbl>
1 <split [1K/252]> Fold1 0.00208
2 <split [1K/252]> Fold2 0.00189
3 <split [1K/252]> Fold3 0.00201
4 <split [1K/252]> Fold4 0.00224
5 <split [1K/251]> Fold5 0.00190</code></pre>
<p>OK, we have five RMSE’s since we ran the model on five separate <code>analysis</code> fold sets and tested on five separate <code>assessment</code> fold sets. Let’s find the average RMSE by taking the <code>mean()</code> of the <code>rmse</code> column. That can help reduce noisiness that resulted from our random creation of those five folds.</p>
<pre class="r"><code>cved_ff %>%
mutate(rmse = map_dbl(cved_ff$splits, model_one)) %>%
summarise(mean_rse = mean(rmse)) </code></pre>
<pre><code># 5-fold cross-validation
# A tibble: 1 x 1
mean_rse
<dbl>
1 0.00202</code></pre>
<p>We now have the mean RMSE after running on our model, <code>lm(returns ~ MKT)</code>, on all five of our folds.</p>
<p>That process for finding the mean RMSE can be applied other models, as well. Let’s suppose we wish to find the mean RMSE for two other models: <code>lm(returns ~ MKT + SMB + HML)</code>, the Fama French three-factor model, and <code>lm(returns ~ MKT + SMB + HML + RMW + CMA</code>, the Fama French five-factor model. By comparing the mean RMSE’s, we can evaluate which model explained the returns of AGG better. Since we’re just adding more and more factors, the models can be expected to get more and more accurate but again, we are exploring the <code>rsample</code> machinery and creating a template where we can pop in whatever models we wish to compare.</p>
<p>First, let’s create two new functions, that follow the exact same code pattern as above but house the three-factor and five-factor models.</p>
<pre class="r"><code>model_two <- function(split) {
split_for_model <- analysis(split)
ff_model <- lm(returns ~ MKT + SMB + HML, data = split_for_model)
holdout <- assessment(split)
rmse <-
ff_model %>%
augment(newdata = holdout) %>%
rmse(returns, .fitted) %>%
pull(.estimate)
}
model_three <- function(split) {
split_for_model <- analysis(split)
ff_model <- lm(returns ~ MKT + SMB + HML + RMW + CMA, data = split_for_model)
holdout <- assessment(split)
rmse <-
ff_model %>%
augment(newdata = holdout) %>%
rmse(returns, .fitted) %>%
pull(.estimate)
}</code></pre>
<p>Now we pass those three models to the same <code>mutate()</code> with <code>map_dbl()</code> flow that we used with just one model. The result will be three new columns of RMSE’s, one for each of our three models applied to our five folds.</p>
<pre class="r"><code>cved_ff %>%
mutate(
rmse_model_1 = map_dbl(
splits,
model_one),
rmse_model_2 = map_dbl(
splits,
model_two),
rmse_model_3 = map_dbl(
splits,
model_three))</code></pre>
<pre><code># 5-fold cross-validation
# A tibble: 5 x 5
splits id rmse_model_1 rmse_model_2 rmse_model_3
* <list> <chr> <dbl> <dbl> <dbl>
1 <split [1K/252]> Fold1 0.00208 0.00211 0.00201
2 <split [1K/252]> Fold2 0.00189 0.00184 0.00178
3 <split [1K/252]> Fold3 0.00201 0.00195 0.00194
4 <split [1K/252]> Fold4 0.00224 0.00221 0.00213
5 <split [1K/251]> Fold5 0.00190 0.00183 0.00177</code></pre>
<p>We can also find the mean RMSE for each model.</p>
<pre class="r"><code>cved_ff %>%
mutate(
rmse_model_1 = map_dbl(
splits,
model_one),
rmse_model_2 = map_dbl(
splits,
model_two),
rmse_model_3 = map_dbl(
splits,
model_three)) %>%
summarise(mean_rmse_model_1 = mean(rmse_model_1),
mean_rmse_model_2 = mean(rmse_model_2),
mean_rmse_model_3 = mean(rmse_model_3))</code></pre>
<pre><code># 5-fold cross-validation
# A tibble: 1 x 3
mean_rmse_model_1 mean_rmse_model_2 mean_rmse_model_3
<dbl> <dbl> <dbl>
1 0.00202 0.00199 0.00192</code></pre>
<p>That code flow worked just fine, but we had to repeat ourselves when creating the functions for each model. Let’s toggle to a flow where we define three models - the ones that we wish to test with via cross-validation and RMSE - then pass those models to one function.</p>
<p>First, we use <code>as.formula()</code> to define our three models.</p>
<pre class="r"><code>mod_form_1 <- as.formula(returns ~ MKT)
mod_form_2 <- as.formula(returns ~ MKT + SMB + HML)
mod_form_3 <- as.formula(returns ~ MKT + SMB + HML + RMW + CMA)</code></pre>
<p>Now we write one function that takes <code>split</code> as an argument, same as above, but also takes <code>formula</code> as an argument, so we can pass it different models. This gives us the flexibility to more easily define new models and pass them to <code>map</code>, so I’ll append <code>_flex</code> to the name of this function.</p>
<pre class="r"><code>ff_rmse_models_flex <- function(split, formula) {
split_for_data <- analysis(split)
ff_model <- lm(formula, data = split_for_data)
holdout <- assessment(split)
rmse <-
ff_model %>%
augment(newdata = holdout) %>%
rmse(returns, .fitted) %>%
pull(.estimate)
}</code></pre>
<p>Now we use the same code flow as before, except we call <code>map_dbl()</code>, pass it our <code>cved_ff$splits</code> object, our new <code>flex</code> function called <code>ff_rmse_models_flex()</code>, and the model we wish to pass as the <code>formula</code> argument. First we pass it <code>mod_form_1</code>.</p>
<pre class="r"><code>cved_ff %>%
mutate(rmse_model_1 = map_dbl(cved_ff$splits,
ff_rmse_models_flex,
formula = mod_form_1))</code></pre>
<pre><code># 5-fold cross-validation
# A tibble: 5 x 3
splits id rmse_model_1
* <list> <chr> <dbl>
1 <split [1K/252]> Fold1 0.00208
2 <split [1K/252]> Fold2 0.00189
3 <split [1K/252]> Fold3 0.00201
4 <split [1K/252]> Fold4 0.00224
5 <split [1K/251]> Fold5 0.00190</code></pre>
<p>Now let’s pass it all three models and find the mean RMSE.</p>
<pre class="r"><code>cved_ff %>%
mutate(rmse_model_1 = map_dbl(cved_ff$splits,
ff_rmse_models_flex,
formula = mod_form_1),
rmse_model_2 = map_dbl(cved_ff$splits,
ff_rmse_models_flex,
formula = mod_form_2),
rmse_model_3 = map_dbl(cved_ff$splits,
ff_rmse_models_flex,
formula = mod_form_3)) %>%
summarise(mean_rmse_model_1 = mean(rmse_model_1),
mean_rmse_model_2 = mean(rmse_model_2),
mean_rmse_model_3 = mean(rmse_model_3))</code></pre>
<pre><code># 5-fold cross-validation
# A tibble: 1 x 3
mean_rmse_model_1 mean_rmse_model_2 mean_rmse_model_3
<dbl> <dbl> <dbl>
1 0.00202 0.00199 0.00192</code></pre>
<p>Alright, that code flow seems a bit more flexible than our original method of writing a function to assess each model. We didn’t do much hard thinking about functional form here, but hopefully this provides a template where you could assess more nuanced models. We’ll get into bootstrapping and time series work next week, then head to Shiny to ring in the New Year!</p>

<div id="analyzing-visual-field-data" class="section level2">
<h2>Analyzing Visual Field Data</h2>
<p>In Part I of this series on statistic in glaucoma, we detailed the use of visual fields for understanding functional vision loss in glaucoma patients. Before discussing a new method for modeling visual field data that accounts for the anatomy of the eye, we discussed how visual field data is typically analyzed by introducing a common diagnostic metric, point-wise linear regression (PLR). PLR is a trend-based diagnostic that uses slope p-values from the location specific linear regressions to discriminate progression status. The motivation for PLR is straightforward, assuming that large negative slopes at numerous visual field locations is indicative of progression. This is characteristic of a large class of methods for analyzing visual field data that attempt to discriminate progression based on changes in the DLS across time. This technique is simple, intuitive, and effective; however, it is often limited due to the naivete of modeling assumptions, including the independence of visual field locations.</p>
</div>
<div id="ocular-anatomy-in-the-neighborhood-structure-of-the-visual-field" class="section level2">
<h2>Ocular Anatomy in the Neighborhood Structure of the Visual Field</h2>
<p>To properly account for the spatial dependencies on the visual field, Berchuck et al. 2018 introduce a neighborhood model that incorporates anatomical information through a dissimilarity metric. Details of the method can be found in Berchuck et al. 2018, but we provide a quick introduction. The key development is the specification of the neighborhood structure through a new definition of adjacency weights. Typically in areal data, the adjacency for two locations <span class="math inline">\(i\)</span> and <span class="math inline">\(j\)</span> is defined as <span class="math inline">\(w_{ij} = 1(i \sim j)\)</span>, where <span class="math inline">\(i \sim j\)</span> is the event that locations <span class="math inline">\(i\)</span> and <span class="math inline">\(j\)</span> are neighbors. As discussed in Part I, this assumption is not sufficient due to the complex anatomy of the eye. To account for this additional structure, a more general adjacency is introduced that is a function of a dissimilarity metric, <span class="math inline">\(w_{ij}(\alpha_t) = 1(i \sim j)\exp\{-z_{ij}\alpha_t\}\)</span>. Here, <span class="math inline">\(z_{ij}\)</span> is a dissimilarity metric that represents the absolute difference between the Garway-Heath angles of locations <span class="math inline">\(i\)</span> and <span class="math inline">\(j\)</span>.</p>
<p>The parameter <span class="math inline">\(\alpha_t\)</span> dictates the importance of the dissimilarity metric at each visual field exam <span class="math inline">\(t\)</span>. When <span class="math inline">\(\alpha_t\)</span> becomes large, the model reduces to an independent process, and as <span class="math inline">\(\alpha_t\)</span> goes to zero, the process becomes the standard spatial model for areal data. Based on the specification of the adjacency weights, <span class="math inline">\(\alpha_t\)</span> has a useful interpretation with respect to deterioration of visual ability. In particular, <span class="math inline">\(\alpha_t\)</span> changing over exams indicates that the neighborhood structure on the visual field is changing, which in turn implies damage to the underlying retinal ganglion cell structure. This observation motivates a diagnostic of progression that quantifies variability in <span class="math inline">\(\alpha_t\)</span> across time. We choose the coefficient of variation (CV) and demonstrate that is a highly significant predictor of progression, and furthermore, independent of trend-based methods such as PLR.</p>
</div>
<div id="navigating-the-womblr-package" class="section level2">
<h2>Navigating the <code>womblR</code> Package</h2>
<p>To make the method available to clinicians, the R package <code>womblR</code> was developed. The package provides a suite of functions that walk a user through the full process of analyzing a series of visual fields from beginning to end. The user interface was modeled after other impactful R packages for Bayesian spatial analysis, including <code>spBayes</code> and <code>CARBayes</code>. The package name combines Hadley’s naming convention for R packages (i.e., ending a package with the letter R) with the name of the author of the seminal paper on boundary detection, originally referred to areal wombling (Womble 1951).</p>
<p>We will now walk through the process of analyzing visual field data, estimating the <span class="math inline">\(\alpha_t\)</span> parameters, and assessing progression status. The main function in <code>womblR</code> is the Spatiotemporal Boundary Detection with Dissimilarity Metric model function (<code>STBDwDM</code>). Inference for the method is obtained through Markov chain Monte Carlo (MCMC), which is a computationally intensive method that iterates between updating individual model parameters until enough posterior samples have been collected post-convergence for making accurate posterior inference. Because of the iterative nature of MCMC, the majority of computation is performed within a <code>for</code> loop, so the package is built on C++ through the packages <code>Rcpp</code> and <code>RcppArmadillo</code>. Because of the increased complexity of writing in C++, the pre- and post-processing of the model are done in <code>R</code> with the <code>for</code> loop implemented in C++. The MCMC method employed in <code>womblR</code> is a Metropolis-Hastings within Gibbs algorithm.</p>
<p>Just as a quick aside, with the more recent advent of probabilistic programming, this model could have been implemented using the Hamiltonian Monte Carlo methods used in software like Stan or PyMC3. These programs do not require the derivation of full conditionals, and push the MCMC algorithm to the background. There is undoubtedly a huge market for this type of software, and it is clearly playing a significant role in the popularization of Bayesian modeling. At the same time, implementing MCMC samplers using <code>Rcpp</code> with traditional MCMC algorithms can be instructive, and for those with experience, nearly as quick of a coding experience.</p>
<p>We now begin by formatting the visual field data for analysis. According to the manual, the observed data <code>Y</code> must first be ordered spatially and then temporally. Furthermore, we will remove all locations that correspond to the natural blind spot (which, in the Humphrey Field Analyzer-II, correspond to locations 26 and 35).</p>
<pre class="r"><code>###Load package
library(womblR)
###Format data
blind_spot <- c(26, 35) # define blind spot
VFSeries <- VFSeries[order(VFSeries$Location), ] # sort by location
VFSeries <- VFSeries[order(VFSeries$Visit), ] # sort by visit
VFSeries <- VFSeries[!VFSeries$Location %in% blind_spot, ] # remove blind spot locations
Y <- VFSeries$DLS # define observed outcome data</code></pre>
<p>Now that we have assigned the observed outcomes to <code>Y</code>, we move onto the temporal variable <code>Time</code>. For visual field data, we define this to be the time from the baseline visit. We obtain the unique days from the baseline visit and scale them to be on the year scale.</p>
<pre class="r"><code>Time <- unique(VFSeries$Time) / 365 # years since baseline visit
print(Time)</code></pre>
<pre><code>## [1] 0.0000000 0.3452055 0.6520548 1.1123288 1.3808219 1.6109589 2.0712329
## [8] 2.3780822 2.5698630</code></pre>
<p>Next, we assign the adjacency matrix and dissimilarity metric (both discussed in Part I).</p>
<pre class="r"><code>W <- HFAII_Queen[-blind_spot, -blind_spot] # visual field adjacency matrix
DM <- GarwayHeath[-blind_spot] # Garway-Heath angles</code></pre>
<p>Now that we have specified the data objects <code>Y</code>, <code>DM</code>, <code>W</code>, and <code>Time</code>, we will customize the objects that characterize Bayesian MCMC methods, in particular, hyperparameters, starting values, Metropolis tuning values, and MCMC inputs. These objects have been detailed previously in the <code>womblR</code> package <a href="https://cran.r-project.org/web/packages/womblR/vignettes/womblR-example.html">vignette</a>, so we will not spend time going over their definitions. We will only note that they are each <code>list</code> objects similar to the <code>spBayes</code> package. We begin by specifying the hyperparameters.</p>
<pre class="r"><code>###Bounds for temporal tuning parameter phi
TimeDist <- abs(outer(Time, Time, "-"))
TimeDistVec <- TimeDist[lower.tri(TimeDist)]
minDiff <- min(TimeDistVec)
maxDiff <- max(TimeDistVec)

PhiLower <- -log(0.95) / maxDiff # longest diff goes up to 95%

T = list(Xi = 4, Psi = diag(3)),
Phi = list(APhi = PhiLower, BPhi = PhiUpper))</code></pre>
<p>Then we specify the starting values for the parameters, Metropolis tuning variances, and MCMC details.</p>
<pre class="r"><code>###Starting values
Starting <- list(Delta = c(3, 0, 0), T = diag(3), Phi = 0.5)
###Metropolis tuning variances

###MCMC inputs
MCMC <- list(NBurn = 10000, NSims = 250000, NThin = 25, NPilot = 20)</code></pre>
<p>We specify that our model will run for a burn-in period of 10,000 scans, followed by 250,000 scans post burn-in. In the burn-in period there will be 20 iterations of pilot adaptation evenly spaced out over the period. The final number of samples to be used for inference will be thinned down to 10,000 based on the thinning number of 25. We can now run the MCMC sampler. Details of the various options available in the sampler can be found in the documentation, <code>help(STBDwDM)</code>.</p>

<p>For this information to be useful clinically, we convert it into a probability of progression based on a model trained on a large cohort of glaucoma patients (Berchuck et al. 2019). Because the information from <span class="math inline">\(\alpha_t\)</span> is independent of trend-based methods, we show that the optimal use of <span class="math inline">\(\alpha_t\)</span> is combining it with a basic global metric that includes the slope and p-value (and their interaction) of the overall mean at each visual field exam. The trained model coefficients are publicly available and are used below. Furthermore, both the mean, standard deviation, and their interaction of the CV of <span class="math inline">\(\alpha_t\)</span> are included. The probability of progression can be calculated as follows.</p>
<pre class="r"><code>###Calculate the global metric slope and p-value
MeanSens <- apply(t(matrix(VFSeries$DLS, ncol = Nu)) / 10, 1, mean) # scaled mean DLS
reg.global <- lm(MeanSens ~ Time) # global regression
GlobalS <- summary(reg.global)$coef[2, 1] # global slope
GlobalP <- summary(reg.global)$coef[2, 4] # global p-value
###Obtain probabiltiy of progression using estimated parameters from Berchuck et al. 2019
input <- c(1, GlobalP, GlobalS, STCV[1], STCV[2], GlobalS * GlobalP, STCV[1] * STCV[2])
coef <- c(-1.7471655, -0.2502131, -13.7317622, 7.4746348, -8.9152523, 18.6964153, -13.3706058)
fit <- input %*% coef
exp(fit) / (1 + exp(fit))</code></pre>
<pre><code>## [,1]
## [1,] 0.4355997</code></pre>
<p>The probability of progression is calculated to be 0.44, which can be compared to the threshold cutoff for the trained model of 0.325. This cutoff for the probability of progression was determined using operating characteristics, so that the specificity was forced to be in the clinically meaningful range of 85%. Based on this derived threshold, the probability of progression is high enough to indicate that this patient’s disease shows evidence of visual field progression (which is reassuring, because we know this patient has progression as determined by clinicians).</p>
<p><code>Looking ahead:</code> The third installment will wrap up the discussion on the <code>womblR</code> package and ponder future directions for the role of statistics in glaucoma research. Furthermore, the role of open-source software in medicine will be discussed.</p>

<h2>Introduction</h2>
<p>Glaucoma is a leading cause of blindness worldwide, with a prevalence of 4% in the population aged 40-80. The disease is characterized by retinal ganglion cell death and corresponding damage to the optic nerve head. Since visual impairment caused by glaucoma is irreversible and efficient treatments exist, early detection of the disease is essential. Determining if the disease is progressing remains one of the most challenging aspects of glaucoma management, since it is difficult to distinguish true progression from variability due to natural degradation or noise. In practice, clinicians monitor progression using a multifactorial approach that relies on various measurements of the disease. In this series of blog posts, we focus on the use of visual fields. Visual field examinations obtain levels of a patient’s actual vision, and the practice is thus referred to as a functional measurement. As such, visual fields are a proxy for a patient’s quality of life, and therefore are typically prioritized in practice.</p>
</div>
<div id="visual-field-data" class="section level2">
<h2>Visual Field Data</h2>
<p>Visual fields are complex spatiotemporal data generated from an intricate anatomical system, which is important to understand for modeling purposes. To illustrate visual field data, we load an example data set from the <code>womblR</code> package on CRAN. The package <code>womblR</code> was developed specifically for analyzing visual field data, and uses a Bayesian hierarchical model that accounts for the complex nature of the data (more details will be provided in Part II). The specific data set comes from the Vein Pulsation Study Trial in Glaucoma and the Lions Eye Institute trial registry, Perth, Western Australia. We begin by loading the package.</p>
<pre class="r"><code>library(womblR)</code></pre>
<p>The data set of interest is loaded lazily and can be accessed as follows; we also view the first six rows for illustration.</p>
<pre class="r"><code>data(VFSeries)
head(VFSeries)</code></pre>
<pre><code>## Visit DLS Time Location
## 1 1 25 0 1
## 2 2 23 126 1
## 3 3 23 238 1
## 4 4 23 406 1
## 5 5 24 504 1
## 6 6 21 588 1</code></pre>
<p>The data object <code>VFSeries</code> contains a longitudinal series of visual fields for a glaucoma patient that we will use throughout the three blog posts to exemplify the study of visual fields. This patient has been determined to be progressing, based on the expertise of two clinicians. <code>VFSeries</code> has four variables: <code>Visit</code>, <code>DLS</code>, <code>Time</code>, and <code>Location</code>. The variable <code>Visit</code> represents the visual field test visit number, <code>DLS</code> the observed measure, <code>Time</code> the time of the visual field test (in days from baseline visit), and <code>Location</code> the spatial location on the visual field where the observation occurred. There are 9 visual field exams contained in this data set, and on average 117.25 days between visits.</p>
<p>To help visualize the dataframe, we can use the <code>PlotVFTimeSeries</code> function. <code>PlotVFTimeSeries</code> is a function that plots a patient’s observed visual acuity over time at each location on the visual field.</p>
<pre class="r"><code>PlotVfTimeSeries(Y = VFSeries$DLS,
Location = VFSeries$Location,
Time = VFSeries$Time,
main = "Visual field sensitivity time series \n at each location",
xlab = "Days from baseline visit",
ylab = "Differential light sensitivity (dB)",
line.reg = FALSE)</code></pre>
<p><img src="/post/2018-11-19-statistics-in-glaucoma-part-i_files/figure-html/unnamed-chunk-3-1.png" width="528" style="display: block; margin: auto;" /></p>
<p>The above figure demonstrates the visual field from a Humphrey Field Analyzer-II (HFA-II) testing machine, which generates 54 spatial locations (only 52 informative locations; note the 2 blanks spots corresponding to the blind spot). The visual field map is constructed by assessing a patient’s response to varying levels of light. Patients are instructed to focus on a central fixation point as light is introduced randomly in a preceding manner over a grid on the visual field. As light is observed, the patient presses a button and the current light intensity is recorded. The process is repeated until the entire visual field is tested. The light intensity is measured in differential light sensitivity (DLS), which quantifies the difference in the HFA-II background and observed light intensity. Smaller values indicate worsening vision.</p>
</div>
<div id="spatial-anatomy-on-the-visual-field" class="section level2">
<h2>Spatial Anatomy on the Visual Field</h2>
<p>The spatial surface of the visual field is observed on a lattice (i.e., uniform areal data); however, it is a complex projection of the underlying optic nerve head and exhibits anatomically induced spatial dependencies. In particular, localized damage to the optic disc can result in clinically deterministic deterioration across the visual field. Incorporating this non-standard spatial dependence structure into our methodology is a priority for properly analyzing these data, although it is commonly ignored. Translating this into math lingo, this means that a naive modeling of the spatial surface of the visual field would be inappropriate (i.e., neighbors defined through adjacent locations). Instead, the definition of a neighbor when considering vision loss on the visual field must depend on the underlying anatomical proximities.</p>
<p>To illustrate this concept, we begin by displaying the visual field neighborhood structure. The adjacency matrix for the HFA-II is available in the <code>womblR</code> package. In this analysis, we use a queen specification, meaning that an adjacency is defined as any location that shares an edge or corner on the lattice. We now load this adjacency matrix and remove the two locations that correspond to the blind spot.</p>
<pre class="r"><code>blind_spot <- c(26, 35) # define blind spot
W <- HFAII_Queen[-blind_spot, -blind_spot] # HFA-II visual field adjacency matrix</code></pre>
<p>This adjacency structure can be displayed using the <code>graph.adjacency</code> function in the <code>igraph</code> package.</p>
<pre class="r"><code>library(igraph)
adj.graph <- graph.adjacency(W, mode = "undirected")
plot(adj.graph)</code></pre>
<p><img src="/post/2018-11-19-statistics-in-glaucoma-part-i_files/figure-html/unnamed-chunk-5-1.png" width="528" style="display: block; margin: auto;" /></p>
<p>As mentioned above, naively assuming that all of these adjacencies are equal ignores the important underlying anatomy that enforces these dependencies. This anatomical relationship of the visual field test points and the underlying optic nerve head was studied by Garway-Heath et al. (2000), in which they estimated the angle that each test location’s underlying retinal ganglion cells enters the optic disc, measured in degrees. These angles are the missing link that will allow the visual field adjacency structure to be dictated by the underlying anatomy. These angles can be visualized using the function <code>PlotAdjacency</code> from <code>womblR</code>, which displays neighborhood structures across the visual field. Before using this function, we need to load the angles measured in Garway-Heath et al. (2000). These are available from <code>womblR</code>; again, we remove the blind spot before using.</p>
<pre class="r"><code>Angles <- GarwayHeath[-blind_spot] # Garway-Heath angles
summary(Angles)</code></pre>
<pre><code>## Min. 1st Qu. Median Mean 3rd Qu. Max.
## 11.00 80.75 192.50 177.35 275.75 329.00</code></pre>
<p>We are now ready to visualize the neighborhood structure of the visual field using the <code>PlotAdjacency</code> function.</p>
<pre class="r"><code>###Plot the angles on the visual field
PlotAdjacency(W = W,
DM = Angles,
zlim = c(0, 180),
Visit = NA,
edgewidth = 3.75,
cornerwidth = 0.33,
lwd.border = 3.75,
main = "Garway-Heath angles\n across the visual field")</code></pre>
<p><img src="/post/2018-11-19-statistics-in-glaucoma-part-i_files/figure-html/unnamed-chunk-7-1.png" width="528" style="display: block; margin: auto;" /></p>
<p>The angles measured by Garway-Heath et al. are presented at each location on the visual field. More interestingly, the distances between these angles are presented for each of the neighbor pairs. This figure is equivalent to the adjacency plot displayed above, but allows the adjacencies to vary as a function of the anatomy. In particular, if two visual field locations are anatomically similar, the dependency is strengthened (i.e., more white), and if the locations are close to anatomically independent, the dependency is weaker (i.e., more black). Here the edge adjacencies are represented by lines, while the diagonal adjacencies are represented as two triangles. This view of the visual field details the anatomical importance in modeling visual field data, as neighboring locations can have underlying retinal ganglion cells that enter the optic nerve head with a large degree of separation. In particular, locations on either side of the equator, although adjacent, are anatomically close to independent based on anatomy.</p>

<h2>How to Model Visual Field Data?</h2>
<p>If you have gotten this far in the post, hopefully you have the sense that the study of visual field data is statistically interesting and clinically important for properly assessing a glaucoma patient’s risk of vision loss. In the next two blog posts, we will explore how visual field data are currently analyzed and new methods that account for the anatomical structure detailed above. To accomplish this, we will break down the algorithm and software used to build the <code>womblR</code> package, and will attempt to illustrate the importance of R packages for open-source clinical research.</p>

CRAN’s New Missing Data Task View
https://rviews.rstudio.com/2018/10/26/cran-s-new-missing-values-task-view/
Fri, 26 Oct 2018 00:00:00 +0000https://rviews.rstudio.com/2018/10/26/cran-s-new-missing-values-task-view/
<p>It is a relatively rare event, and cause for celebration, when CRAN gets a new Task View. This week the <a href="https://github.com/R-miss-tastic">r-miss-tastic</a> team: Julie Josse, Nicholas Tierney and Nathalie Vialaneix launched the <a href="https://CRAN.R-project.org/view=MissingData">Missing Data Task View</a>. Even though I did some research on R packages for a <a href="https://rviews.rstudio.com/2016/11/30/missing-values-data-science-and-r/">post on missing values</a> a couple of years ago, I was dumbfounded by the number of packages included in the new Task View.</p>
<iframe src="https://cran.r-project.org/view=MissingData" width="90%" height="300"> </iframe>
<hr />
<p>This single page not only describes what R has to offer with respect to coping with missing data, it is probably the world’s most complete index of statistical knowledge on the subject. But, the task view is not just devoted to esoterica. The <em>Exploration of missing data</em> section contains a number of tools that should be useful in any data wrangling effort like this plot diagnostic plot from the <code>dlookr</code> package.</p>
<p><img src="/post/2018-10-25-Missing-Values_files/dlookr.png" height = "300" width=90%></p>
<p>The downside that may curb one’s enthusiasm, is that mastering missing data techniques requires some serious study. Missing data problems are among the most vexing in statistics, and the newer techniques for tackling these problems are relatively sophisticated. So, unless you are a <code>na.omit()</code> kind of guy/gal (a data scientist?) coming to grips with <code>NAs</code> may involve a subtle inferential task embedded in the usual data wrangling effort.</p>
<p>It is also the case that it is not easy to find good introductory material on the subject. The notable exception is Stef van Buuren’s authoritative R-based textbook, <a href="https://stefvanbuuren.name/fimd/">Flexible Imputation of Missing Data</a> which he has graciously made available online.</p>
<p>I also found the review papers by <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3701793/">Dong and Peng</a> and by <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1839993/">Horton and Kleinman</a> to be helpful. And, if you read French a little better than I do, the review by <a href="http://journal-sfds.fr/article/view/681">Imbert and Vialaneix</a> looks like it covers all of the basic material.</p>
<p>Finally, I should mention that the Missing Data Task View is part of the R Consortium funded project <a href="https://www.r-consortium.org/projects/awarded-projects">A unified platform for missing values methods and workflows</a>. Many thanks to the ISC for making it possible for the expert r-miss-tastic team to do the work.</p>

<hr />
<p>Searching for R packages is a vexing problem for both new and experienced R users. With over 13,000 packages already on <a href="https://cran.r-project.org/web/packages/">CRAN</a>, and new packages arriving at a rate of almost 200 per month, it is impossible to keep up. Package names can be almost anything, and they are rarely informative, so <a href="https://cran.r-project.org/web/packages/available_packages_by_name.html">searching by name</a> is of little help. I make it a point to look at all of the new packages arriving on CRAN each month, but after a month or so, when asked about packages related to some particular topic, more often than not, I have little more to offer than a vague memory that I saw something that might be useful.</p>
<p>Fortunately, package developers have provided some very useful tools, if you know where to look. :) This post presents a search strategy based on some relatively new packages I have come across in my monthly review.</p>
<pre class="r"><code>library(tidyverse)</code></pre>
<pre><code>## ── Attaching packages ───────────────────────────────────────────── tidyverse 1.2.1 ──</code></pre>
<pre><code>## ✔ ggplot2 2.2.1 ✔ purrr 0.2.4
## ✔ tibble 1.4.2 ✔ dplyr 0.7.5
## ✔ tidyr 0.8.1 ✔ stringr 1.3.1
## ✔ readr 1.1.1 ✔ forcats 0.3.0</code></pre>
<pre><code>## ── Conflicts ──────────────────────────────────────────────── tidyverse_conflicts() ──
## ✖ dplyr::filter() masks stats::filter()
## ✖ dplyr::lag() masks stats::lag()</code></pre>
<pre class="r"><code>library(packagefinder)
library(dlstats)
library(cranly)</code></pre>
<p><a href="https://CRAN.R-project.org/package=packagefinder">packagefinder v0.0.7</a>, which appeared on CRAN this past July, goes right to the heart of the problem and shows great promise. The function <code>findPackage()</code> allows you to do a keyword search through the metadata of all CRAN packages. Since I am researching a possible post on <a href="https://thomasleeper.com/Rcourse/Tutorials/permutationtests.html">Permutation Tests</a>, I thought I would give <code>packagefinder::findPackage()</code> the most straightforward search text I could think of. (Note that the link for <code>Permutation Tests</code> above goes to an example by Thomas Leeper that references the <code>coin</code> package. This is a pretty strong hint that I expect to find <code>coin</code> prominently listed among the results.)</p>
<p>Also note, that making the output a <code>tibble</code> is not just obsessive-compulsive tidy behavior. The default print method sends the output to the Viewer in the RStudio IDE.</p>
<pre class="r"><code>pt_pkg <- as.tibble(findPackage("permutation test"))</code></pre>
<pre><code>##
## 59 out of 13256 CRAN packages found in 6 seconds.</code></pre>
<pre class="r"><code>pt_pkg</code></pre>
<pre><code>## # A tibble: 59 x 5
## SCORE NAME DESC_SHORT DOWNL_TOTAL GO
## <dbl> <chr> <chr> <S3: format> <fct>
## 1 100 permutes Permutation Tests for Time Series … NA 8300

## 9 75 RATest Randomization Tests NA 9287
## 10 75 treeperm Exact and Asymptotic K Sample Perm… NA 12442
## # ... with 49 more rows</code></pre>
<p>Unfortunately, the package is very new and not well-documented. It is not clear how <code>SCORE</code> is computed, and <code>DOWNL_TOTAL</code> is replete with <code>NA</code>s. Nevertheless, the function does seem to find packages. I can’t vouch for its completeness, but when I tried it out on some topics with which it I am familiar, it did a pretty thorough job. Note that <code>findPackage()</code> allows a user to set a weights parameter that affects how the search “hits in the package’s title, short description and long description”. So far, I have not found this to be particularly useful, but I have not spent a lot of time with it, either.</p>
<p>The next line of code just selects the columns we will be using.</p>
<pre class="r"><code>pt_pkg <- select(pt_pkg, NAME, DESC_SHORT)</code></pre>
<p>Now that we have a list of packages of interest, it would be nice to have an indication of the quality and usefulness of the packages selected. A natural measure of usefulness is the number of times the package has been downloaded. For this, we turn to the <code>cran_stats()</code> function from the <a href="https://cran.r-project.org/package=dlstats"><code>dlstats</code> package</a>. This function takes a vector of packages names as inputs, queries the <a href="http://cran-logs.rstudio.com/">RStudio download logs</a>, and returns a data frame listing the number of downloads by month for each package.</p>
<pre class="r"><code>pt_downloads <- cran_stats(pt_pkg$NAME)
dim(pt_downloads)</code></pre>
<pre><code>## [1] 2784 4</code></pre>
<pre class="r"><code>head(pt_downloads)</code></pre>
<pre><code>## start end downloads package
## 4485 2018-05-01 2018-05-31 52 permutes
## 4544 2018-06-01 2018-06-30 89 permutes
## 4603 2018-07-01 2018-07-31 92 permutes
## 4662 2018-08-01 2018-08-31 74 permutes
## 4721 2018-09-01 2018-09-30 227 permutes
## 4780 2018-10-01 2018-10-22 142 permutes</code></pre>
<p>Just a little wrangling yields a data frame that lists total downloads for each package over its lifespan.</p>
<pre class="r"><code>top_downloads <- pt_downloads %>% group_by(package) %>%
summarize(downloads = sum(downloads)) %>%
arrange(desc(downloads))
head(top_downloads,10)</code></pre>
<pre><code>## # A tibble: 10 x 2
## package downloads
## <fct> <int>
## 1 coin 1103426
## 2 exactRankTests 137674
## 3 RVAideMemoire 108837
## 4 perm 97071
## 5 logcondens 83033
## 6 HardyWeinberg 55735
## 7 biotools 47694
## 8 smacof 45257
## 9 SNPassoc 38920
## 10 broman 30956</code></pre>
<p>As expected, <code>coin</code> has flipped to the head of the list. Plotting the downloads over time shows that the package has increased in popularity over the past five years, and it looks like people have been doing a crazy amount of permutation testing over the past year or so.</p>
<pre class="r"><code>top_pkgs <- pt_downloads %>% filter(package %in% top_downloads$package[1:3])
ggplot(top_pkgs, aes(end, downloads, group=package, color=package)) +
geom_line() + geom_point(aes(shape=package))</code></pre>
<p><img src="/post/2018-10-17-searching-for-r-packages_files/figure-html/unnamed-chunk-7-1.png" width="672" /></p>
<p>One way to gauge the quality and reliability of a package is to see how many other packages depend on it. These would be the packages listed as “Reverse depends” and “Reverse imports” on the CRAN page for a package. Using the canonical link, <a href="https://cran.r-project.org/package=coin" class="uri">https://cran.r-project.org/package=coin</a>, we see that 24 packages are listed in these fields on the <code>coin</code> page.</p>
<p>Likewise, knowing something of an author’s background, his or her experience writing other R packages, and prominent R developers he or she may have collaborated with is also helpful in assessing whether to give a newly found package is worth a try. The same link above also shows the package’s authors. Checking the <a href="http://www.cran.r-project.org/contributors.html">Contributors page</a> for the R Project, we see that two authors are members of R Core and the lead author, Torsten Hothorn, is listed with the contributors who have provided “invaluable help”. The background and collaborators couldn’t be better.</p>
<p>In most cases, background checks aren’t so easy. However, with the help of the <code>build_network()</code> function from the <a href="https://cran.r-project.org/web/packages/cranly/index.html">cranly package</a>, it is simple to track down an author’s collaboration network. Here, we see that Torston has an extensive network of collaborators.</p>
<pre class="r"><code>p_db <- tools::CRAN_package_db()
clean_p_db <- clean_CRAN_db(p_db)
author_net <- build_network(object = clean_p_db, perspective = "author")
plot(author_net, author = "Torsten Hothorn", exact = FALSE)</code></pre>

<p>It is also helpful to know who the most prolific CRAN package authors are. You can generally count on packages from this crew being top-shelf.</p>
<pre class="r"><code>author_summary <- summary(author_net)</code></pre>
<pre><code>## Warning in closeness(cranly_graph, normalized = FALSE): At centrality.c:
## 2784 :closeness centrality is not well-defined for disconnected graphs</code></pre>
<pre class="r"><code>plot(author_summary)</code></pre>

<p>I am not claiming that the path I have taken here is the best, or even unique. I have by no means exhausted the possibilities with the packages I have highlighted. Previous posts explore <a href="https://rviews.rstudio.com/2018/05/31/exploring-r-packages/">cranly</a> and the <code>tools::CRAN_package_db()</code> function in a little more depth, but there is much more to explore.</p>
<p>Finally, it would be remiss of me not to mention that the first thing anyone, novice or expert, should do when looking for a package to solve some new problem, or even to get an indication of the quality of a package, is to examine the <a href="https://cran.r-project.org/web/views/">CRAN Task Views</a>. These are lists of packages curated by experts and organized into functional areas. With just a little searching, you will see that <code>coin</code> shows up in multiple task views.</p>

<p>September was another relatively slow month for new package activity on CRAN: “only” 126 new packages by my count. My Top 40 list is heavy on what I characterize as “utilities”: packages that either extend R in some fashion or make it easier to do things in R. This month, the packages I selected fall into eight categories: Data, Finance, Machine Learning, Science, Statistics, Time Series, Utilities and Visualization.</p>

JSM 2018 Itinerary
https://rviews.rstudio.com/2018/07/25/jsm-2018-itinerary/
Wed, 25 Jul 2018 00:00:00 +0000https://rviews.rstudio.com/2018/07/25/jsm-2018-itinerary/
<p>JSM 2018 is almost here! Usually around this time, I comb through the entire program manually making an itinerary for myself. But this year I decided to try something new – a programmatic way of going through the program, and then building a Shiny app that helps me better navigate the online program.</p>
<p>The end result of the app is below. (I might tweak it a bit further after this post goes live, depending on feedback I receive.) You can interact with the app <a href="https://minecr.shinyapps.io/jsm2018-schedule/">here</a>.</p>
<p>I’m often dissatisfied with conference webpages, and almost always dissatisfied with conference apps, so I thought this was a good opportunity to build one myself. Also, I’m teaching Shiny at JSM and have been wanting to acquaint myself better with the <a href="http://glue.tidyverse.org/">glue</a> package, so I figured spending some time web scraping, text wrangling, and building an app could be fun. (Note to self: Next time do this <em>after</em> you’re done preparing all your presentations!)</p>
<p>This is a three part blog post: (1) the data, (2) the app, and (3) the itinerary.</p>
<p>All relevant source code can be found <a href="https://github.com/mine-cetinkaya-rundel/jsm2018-schedule">here</a>.</p>
<div id="the-data" class="section level2">
<h2>The data</h2>
<p>The data were scraped from the <a href="http://ww2.amstat.org/meetings/jsm/2018/onlineprogram/index.cfm">JSM 2018 Online Program</a>.</p>
<p>Before scraping the data, I checked that the scraping is allowed on this page using <code>robotstxt::paths_allowed()</code>.</p>
<pre class="r"><code>library(robotstxt)
paths_allowed("http://ww2.amstat.org/meetings/jsm/2018/onlineprogram/index.cfm")</code></pre>
<pre><code>##
ww2.amstat.org No encoding supplied: defaulting to UTF-8.</code></pre>
<pre><code>## [1] TRUE</code></pre>
<p>Looks like we’re good to go!</p>
<p>Once you’re on the online program <a href="http://ww2.amstat.org/meetings/jsm/2018/onlineprogram/index.cfm">landing page</a>, you need to click Search without setting any search parameters in order to get to a page with information on all JSM sessions. For convenience, I saved the resulting HTML file for this page in my repo. (You can access it <a href="https://github.com/mine-cetinkaya-rundel/jsm2018-schedule/blob/master/data/jsm2018.html">here</a>.)</p>
<p>The next step is using <a href="https://github.com/hadley/rvest">rvest</a> and the <a href="https://selectorgadget.com/">SelectorGadget</a> to scrape the data. This process allows us to take not-so-tidy data from the web and turn it into a tidy data frame that we can then work with in R.</p>
<div class="figure">
<img src="/post/2018-07-25-jsm-2018-itinerary_files/data-scrape.png" />
</div>
<p>Based on these data, I created two data frames: one for sessions and the other for talks. These two data frames will serve as the source data for the two tabs in the app. The code for data scraping the data and wrangling into these two data frames can be found <a href="https://github.com/mine-cetinkaya-rundel/jsm2018-schedule/blob/master/scrape.R">here</a>.</p>
</div>
<div id="the-app" class="section level2">
<h2>The app</h2>
<p>The app is built with Shiny, using a <code>navbarPage</code> to allow for two separate <code>tabPanel</code>s.</p>
<p>The first panel is the session schedule. This tab allows users to subset sessions based on days and times, as well as session sponsors and types. This is similar to the functionality on the JSM page; however, it’s designed to easily subset for sessions I like having on my radar, and it allows me to subset by time of day.</p>
<div class="figure">
<img src="/post/2018-07-25-jsm-2018-itinerary_files/jsm2018-app-sessions.png" />
</div>
<p>The second tab is designed to navigate talks, as opposed to sessions. You can look for keywords in talk titles. Curious how many talks have “R” in their title? How about “tidy”? Take a guess first, then peek at <a href="https://minecr.shinyapps.io/jsm2018-schedule/">the app</a> to check your answer.</p>
<div class="figure">
<img src="/post/2018-07-25-jsm-2018-itinerary_files/jsm2018-app-talks.png" />
</div>
<p>The source code for the app can be found <a href="https://github.com/mine-cetinkaya-rundel/jsm2018-schedule/blob/master/app.R">here</a>.</p>
</div>
<div id="the-itinerary" class="section level2">
<h2>The itinerary</h2>
<p>Using a combination of the app I build and good ol’ Ctrl-F on the online program, I came up with the following itinerary for JSM. The foci of the sessions I selected are education, data science, computing, visualization, and social responsibility. I obviously won’t make it to all the sessions I list here, but I plan to at least try to get my hands on the slides for the talks I don’t make.</p>
<p>I also plan on stopping by the <a href="https://ww2.amstat.org/meetings/jsm/2018/dataartshow.cfm">JSM Data Art Show</a> at some point!</p>
<p>If you have suggestions for other sessions (in these topics or other) that you think should be on this list, let me know in the comments!</p>

CVXR: A Direct Standardization Example
https://rviews.rstudio.com/2018/07/20/cvxr-a-direct-standardization-example/
Fri, 20 Jul 2018 00:00:00 +0000https://rviews.rstudio.com/2018/07/20/cvxr-a-direct-standardization-example/
<p>In our <a href="https://rviews.rstudio.com/2017/11/27/introduction-to-cvxr/">first blog post</a>, we introduced <code>CVXR</code>, an R package for disciplined convex optimization, and showed how to model and solve a non-negative least squares problem using its interface. This time, we will tackle a non-parametric estimation example, which features new atoms as well as more complex constraints.</p>
<div id="direct-standardization" class="section level2">
<h2>Direct Standardization</h2>
<p>Consider a set of observations <span class="math inline">\((x_i,y_i)\)</span> drawn non-uniformly from an unknown distribution. We know the expected value of the columns of <span class="math inline">\(X\)</span>, denoted by <span class="math inline">\(b \in {\mathbf R}^n\)</span>, and want to estimate the true distribution of <span class="math inline">\(y\)</span>. This situation may arise, for instance, if we wish to analyze the health of a population based on a sample skewed toward young males, knowing the average population-level sex, age, etc.</p>
<p>A naive approach would be to simply take the empirical distribution that places equal probability <span class="math inline">\(1/m\)</span> on each <span class="math inline">\(y_i\)</span>. However, this is not a good estimation strategy when our sample is unbalanced. Instead, we will use the method of <strong>direct standardization</strong> (Fleiss, Levin, and Paik 2003, 19.5): we solve for weights <span class="math inline">\(w \in {\mathbf R}^m\)</span> of a weighted empirical distribution, <span class="math inline">\(y = y_i\)</span> with probability <span class="math inline">\(w_i\)</span>, which rectifies the skewness of the sample. This can be posed as the convex optimization problem</p>
<p><span class="math display">\[
\begin{array}{ll} \underset{w}{\mbox{maximize}} & \sum_{i=1}^m -w_i\log w_i \\
\mbox{subject to} & w \geq 0, \quad \sum_{i=1}^m w_i = 1,\quad X^Tw = b.
\end{array}
\]</span></p>
<p>Our objective is the total entropy, which is concave on <span class="math inline">\({\mathbf R}_+^m\)</span>. The constraints ensure <span class="math inline">\(w\)</span> is a probability vector that induces our known expectations over the columns of <span class="math inline">\(X\)</span>, i.e., <span class="math inline">\(\sum_{i=1}^m w_iX_{ij} = b_j\)</span> for <span class="math inline">\(j = 1,\ldots,n\)</span>.</p>
</div>
<div id="an-example-with-simulated-data" class="section level2">
<h2>An Example with Simulated Data</h2>
<p>As an example, we generate <span class="math inline">\(m = 1000\)</span> data points <span class="math inline">\(x_{i,1} \sim \mbox{Bernoulli}(0.5)\)</span>, <span class="math inline">\(x_{i,2} \sim \mbox{Uniform}(10,60)\)</span>, and <span class="math inline">\(y_i \sim N(5x_{i,1} + 0.1x_{i,2},1)\)</span>. We calculate <span class="math inline">\(b_j\)</span> to be the mean over <span class="math inline">\(x_{.,j}\)</span> for <span class="math inline">\(j = 1,2\)</span>. Then we construct a skewed sample of <span class="math inline">\(m = 100\)</span> points that over-represent small values of <span class="math inline">\(y_i\)</span>, thus biasing its distribution downwards.</p>
<p>Using <code>CVXR</code>, we construct the direct standardization problem. We first define the variable <span class="math inline">\(w\)</span>.</p>
<pre class="r"><code>w <- Variable(m)</code></pre>
<p>Then, we form the objective function by combining <code>CVXR</code>’s library of operators and atoms.</p>
<pre class="r"><code>objective <- Maximize(sum(entr(w)))</code></pre>
<p>Here, <code>entr</code> is the element-wise entropy atom; the S4 object <code>entr(w)</code> represents an <span class="math inline">\(m\)</span>-dimensional vector with entries <span class="math inline">\(-w_i\log(w_i)\)</span> for <span class="math inline">\(i=1,\ldots,m\)</span>. The <code>sum</code> operator acts exactly as expected, forming an expression that is the sum of the entries in this vector. (For a full list of atoms, see the <a href="http://cvxr.rbind.io/post/cvxr_functions/">function reference</a> page).</p>
<p>Our next step is to generate the list of constraints. Note that, by default, the relational operators apply over all entries in a vector or matrix.</p>
<pre class="r"><code>constraints <- list(w >= 0, sum(w) == 1, t(X) %*% w == b)</code></pre>
<p>Finally, we are ready to formulate and solve the problem.</p>
<pre class="r"><code>prob <- Problem(objective, constraints)
result <- solve(prob)
weights <- result$getValue(w)</code></pre>
<p>Using our optimal <code>weights</code>, we can then re-weight our skewed sample and compare it to the population distribution. Below, we plot the density functions using linear approximations for the range of <span class="math inline">\(y\)</span>.</p>
<pre class="r"><code>## Approximate density functions
dens1 <- density(ypop)
dens2 <- density(y)
dens3 <- density(y, weights = weights)
yrange <- seq(-3, 15, 0.01)
d <- data.frame(x = yrange,
True = approx(x = dens1$x, y = dens1$y, xout = yrange)$y,
Sample = approx(x = dens2$x, y = dens2$y, xout = yrange)$y,
Weighted = approx(x = dens3$x, y = dens3$y, xout = yrange)$y)

<p>As is clear from the plots, the sample probability distribution peaks around <span class="math inline">\(y = 2.0\)</span>, and its cumulative distribution is shifted left from the population’s curve, a result of the downward bias in our sampled <span class="math inline">\(y_i\)</span>. However, with the direct standardization weights, the new empirical distribution cleaves much closer to the true distribution shown in red.</p>

Solver Interfaces in CVXR
https://rviews.rstudio.com/2018/07/09/solver-interfaces-in-cvxr/
Mon, 09 Jul 2018 00:00:00 +0000https://rviews.rstudio.com/2018/07/09/solver-interfaces-in-cvxr/
<h2 id="introduction">Introduction</h2>
<p>In our <a href="https://rviews.rstudio.com/2017/11/27/introduction-to-cvxr/">previous blog
post</a>, we
introduced <code>CVXR</code>, an R package for disciplined convex
optimization. The package allows one to describe an optimization
problem with <a href="http://dcp.stanford.edu">Disciplined Convex Programming</a>
rules using high level mathematical syntax. Passing this problem
definition along (with a list of constraints, if any) to the <code>solve</code>
function transforms it into a form that can be handed off to
a solver. The default installation of <code>CVXR</code> comes with two (imported)
open source solvers:</p>
<ul>
<li><a href="https://github.com/embotech/ecos">ECOS</a> and its mixed integer
cousin <code>ECOS_BB</code> via the CRAN package
<a href="https://cloud.r-project.org/package=ECOSolveR">ECOSolveR</a></li>
<li><a href="https://github.com/cvxgrp/scs">SCS</a> via the CRAN package
<a href="https://cloud.r-project.org/package=scs">scs</a>.
<br /></li>
</ul>
<p><code>CVXR</code> (version 0.99) can also make use of several other open source
solvers implemented in R packages:</p>
<ul>
<li>The linear and mixed integer programming package
<a href="http://lpsolve.sourceforge.net/5.5/"><code>lpSolve</code></a> via the
<a href="https://cloud.r-project.org/package=lpSolveAPI"><code>lpSolveAPI</code></a> package</li>
<li>The linear and mixed integer programming package <a href="https://www.gnu.org/software/glpk/"><code>GLPK</code></a> via the
<a href="https://cloud.r-project.org/package=Rglpk"><code>Rglpk</code></a> package.
<br /></li>
</ul>
<h2 id="about-solvers">About Solvers</h2>
<p>The real work of finding a solution is done by solvers, and writing
good solvers is hard work. Furthermore, some solvers work particularly
well for certain types of problems (linear programs, quadratic
programs, etc.). Not surprisingly, there are commercial vendors who
have solvers that are designed for performance and scale. Two
well-known solvers are <a href="https://www.mosek.com">MOSEK</a> and
<a href="https://www.gurobi.com">GUROBI</a>. R packages for these solvers are
also provided, but they require the problem data to be constructed in
a specific form. This necessitates a bit of work in the current version of
<code>CVXR</code> and is certainly something we plan to include in future versions.
However, it is also true that these commercial solvers expose a much
richer API to Python programmers than to R programmers. How, then, do we
interface such solvers with R as quickly as possible, at least
in the short term?</p>
<h2 id="reticulate-to-the-rescue">Reticulate to the Rescue</h2>
<p>The current version of <code>CVXR</code> exploits the
<a href="https://cran.r-project.org/package=reticulate"><code>reticulate</code></a> package
for commercial solvers such as MOSEK and GUROBI. We took the Python solver interfaces in <a href="http://www.cvxpy.org/versions/0.4.11/index.html"><code>CVXPY</code> version
0.4.11</a>, edited them
suitably to make them self-contained, and hooked them up to <code>reticulate</code>.</p>
<p>This means that one needs two prerequisites to use these commercial solvers in the current version of <code>CVXR</code>:</p>
<ul>
<li>A Python installation</li>
<li>The <a href="https://cran.r-project.org/package=reticulate"><code>reticulate</code></a> R
package.</li>
</ul>
<h2 id="installing-mosek-gurobi">Installing MOSEK/GUROBI</h2>
<p>Both <a href="https://www.mosek.com">MOSEK</a> and
<a href="https://www.gurobi.com">GUROBI</a> provide academic versions
(registration required) free of charge. For example,
<a href="https://www.anaconda.com">Anaconda</a> users can install MOSEK with the command:</p>
<pre><code class="language-bash,">conda install -c mosek mosek
</code></pre>
<p>Others can use the <code>pip</code> command:</p>
<pre><code class="language-bash,">pip install -f https://download.mosek.com/stable/wheel/index.html Mosek
</code></pre>
<p>GUROBI is handled in a similar fashion. The solvers must be activated using a
license provided by the vendor.</p>
<p>Once activated, one can check that <code>CVXR</code> recognizes the solver;
<code>installed_solvers()</code> should list them.</p>
<pre><code>> installed_solvers()

</code></pre>
<h2 id="further-information">Further information</h2>
<p>More information on these solvers, along with a number of tutorial examples are
available on the <a href="https://cvxr.rbind.io">CVXR</a> site. If you are

A First Look at NIMBLE
https://rviews.rstudio.com/2018/07/05/a-first-look-at-nimble/
Thu, 05 Jul 2018 00:00:00 +0000https://rviews.rstudio.com/2018/07/05/a-first-look-at-nimble/
<p>Writing a domain-specific language (DSL) is a powerful and fairly common method for extending the R language. Both <code>ggplot2</code> and <code>dplyr</code>, for example, are DSLs. (See Hadley’s <a href="http://adv-r.had.co.nz/dsl.html">chapter in Advanced R</a> for some elaboration.) In this post, I take a first look at <a href="https://CRAN.R-project.org/package=nimble"><code>NIMBLE</code></a> (Numerical Inference for Statistical Models using Bayesian and Likelihood Estimation), a DSL for formulating and efficiently solving statistical models in general, and Bayesian hierarchical models in particular. The latter comprise a class of interpretable statistical models useful for both inference and prediction. (See Gelman’s 2006 <a href="http://www.stat.columbia.edu/~gelman/research/published/multi2.pdf">Technographics paper</a> for what these models can and cannot do.)</p>
<p>Most of what I describe here can be found in the comprehensive and the very readable <a href="https://arxiv.org/pdf/1505.05093.pdf">paper</a> by Valpine et al., or the extensive <a href="https://r-nimble.org/manuals/NimbleUserManual.pdf">NIMBLE User Manual</a>.</p>
<p>At the risk of oversimplification, it seems to me that the essence of the NIMBLE is that it is a system for developing models designed around two dichotomies. The first dichotomy is that NIMBLE separates the specification of a model from the implementation of the algorithms that express it. A user can formulate a model in the <a href="http://www.openbugs.net/w/FrontPage"><code>BUGS</code></a> language, and then use different NIMBLE functions to solve the model. Or, looking at things the other way round, a user can write a NIMBLE function to implement some algorithm or another efficiently, and then use this function in different models.</p>
<p>The second dichotomy separates model setup from model execution. NIMBLE programming is done by writing <code>nimbleFunctions</code> (see <a href="https://r-nimble.org/manuals/NimbleUserManual.pdf">Chapter 11 of the Manual</a>), a subset of the R Language that is augmented with additional data structures and made compilable. <code>nimbleFunctions</code> come in two flavors. <strong>Setup</strong> functions run once for each model, node any model structure used to define the model. <strong>Run</strong> functions can be executed by R or compiled into C++ code.</p>
<p>NIMBLE is actually more complicated, or should I say “richer”, than this. There are many advanced programming concepts to wrap your head around. Nevertheless, it is pretty straightforward to start using NIMBLE for models that already have <code>BUGS</code> implementations. The best way to get started for anyone new to Bayesian statistics, or whose hierarchical model building skills may be a bit rusty, is to take the advice of the NIMBLE developers and work through the Pump Model example in Chapter 2 of the manual. In the rest of this post, I present an abbreviated and slightly reworked version of that model.</p>
<p>Before getting started, note that although NIMBLE is an <a href="https://cran.r-project.org/package=nimble">R package</a> listed on CRAN, and it installs like any other R package, you must have a C++ compiler and the standard <code>make</code> utility installed on your system before installing NIMBLE. (See Chapter 4 of the manual for platform-specific installation instructions.)</p>
<div id="pump-failure-model" class="section level3">
<h3>Pump Failure Model</h3>
<p>The Pump Failure model is discussed by George et al. in their 1993 paper: <a href="https://www.jstor.org/stable/4616270?seq=1#page_scan_tab_contents">Conjugate Likelihood Distributions</a>. The paper examines Bayesian models that use conjugate priors, but which do not have closed form solutions when prior distributions are associated with the hyperparameters. The <code>BUGS</code> solution of the problem is given <a href="http://www.openbugs.net/Examples/Pumps.html">here</a>.</p>
<p>The data driving the model are: <code>x[i]</code> the number of failures for pump, <code>i</code> in a time interval, <code>t[i]</code> where <code>i</code> goes from 1 to 10.</p>
<pre class="r"><code>library(nimble)
library(igraph)
library(tidyverse)
pumpConsts <- list(N = 10,
t = c(94.3, 15.7, 62.9, 126, 5.24,31.4, 1.05, 1.05, 2.1, 10.5))
pumpData <- list(x = c(5, 1, 5, 14, 3, 19, 1, 1, 4, 22))</code></pre>
<p>Arrival times are a Poisson distribution with parameter <code>lambda</code>, where <code>lambda</code> is itself modeled as a Gamma distribution with hyperparameters <code>alpha</code> and <code>beta</code>.</p>
<p>The model is expressed in the <code>BUGS</code> language wrapped inside the NIMBLE function <code>nimbleCode()</code>, which turns the <code>BUGS</code> code into a object that can be operated on by <code>nimbleModel()</code></p>
<pre class="r"><code>pumpCode <- nimbleCode(
{
for (i in 1:N){
theta[i] ~ dgamma(alpha,beta)
lambda[i] <- theta[i]*t[i]
x[i] ~ dpois(lambda[i])
}
alpha ~ dexp(1.0)
beta ~ dgamma(0.1,1.0)
})
pumpInits <- list(alpha = 1, beta = 1,
theta = rep(0.1, pumpConsts$N))</code></pre>
<p><code>nimbleModel()</code> produces the model object that can be executed by <code>R</code> or compiled.</p>
<pre class="r"><code>pump <- nimbleModel(code = pumpCode, name = "pump", constants = pumpConsts,
data = pumpData, inits = pumpInits)</code></pre>
<p>The following command lets us look at the nodes that comprise the model’s directed graph, and plot it.</p>
<pre class="r"><code>pump$getNodeNames()</code></pre>
<pre><code> [1] "alpha" "beta" "lifted_d1_over_beta"
[4] "theta[1]" "theta[2]" "theta[3]"

[13] "theta[10]" "lambda[1]" "lambda[2]"

[19] "lambda[6]" "lambda[7]" "lambda[8]"
[22] "lambda[9]" "lambda[10]" "x[1]"
[25] "x[2]" "x[3]" "x[4]"
[28] "x[5]" "x[6]" "x[7]"
[31] "x[8]" "x[9]" "x[10]" </code></pre>
<pre class="r"><code>pump$plotGraph()</code></pre>
<p><img src="/post/2018-06-12-a-first-look-at-nimble_files/figure-html/unnamed-chunk-5-1.png" width="672" /></p>
<p>We can look at the values stored at each node. The node for <code>x</code> contains the initial values we entered into the model and the nodes for <code>theta</code> and <code>lambda</code> contain the initial calculated values</p>
<pre class="r"><code>pump$x</code></pre>
<pre><code> [1] 5 1 5 14 3 19 1 1 4 22</code></pre>
<pre class="r"><code>pump$theta</code></pre>
<pre><code> [1] 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1</code></pre>
<pre class="r"><code>pump$lambda</code></pre>
<pre><code> [1] 9.430 1.570 6.290 12.600 0.524 3.140 0.105 0.105 0.210 1.050</code></pre>
<p>We can also look at the log probabilities of the likelihoods.</p>
<pre class="r"><code>pump$logProb_x</code></pre>
<pre><code> [1] -2.998011 -1.118924 -1.882686 -2.319466 -4.254550 -20.739651
[7] -2.358795 -2.358795 -9.630645 -48.447798</code></pre>
<p>Next, we use the model to simulate new values for <code>theta</code> and update the variables.</p>
<pre class="r"><code>set.seed(1)
pump$simulate("theta")
pump$theta</code></pre>
<pre><code> [1] 0.15514136 1.88240160 1.80451250 0.83617765 1.22254365 1.15835525
[7] 0.99001994 0.30737332 0.09461909 0.15720154</code></pre>
<p>These new values will, of course, lead to new values of <code>lambda</code> and the log probabilities.</p>
<pre class="r"><code>pump$lambda</code></pre>
<pre><code> [1] 9.430 1.570 6.290 12.600 0.524 3.140 0.105 0.105 0.210 1.050</code></pre>
<pre class="r"><code>pump$logProb_x</code></pre>
<pre><code> [1] -2.998011 -1.118924 -1.882686 -2.319466 -4.254550 -20.739651
[7] -2.358795 -2.358795 -9.630645 -48.447798</code></pre>
<p>The model can also be compiled. The C++ code generated is loaded back into R with an object that can be examined like the uncompiled model.</p>
<pre class="r"><code>Cpump <- compileNimble(pump)
Cpump$theta</code></pre>
<pre><code> [1] 0.15514136 1.88240160 1.80451250 0.83617765 1.22254365 1.15835525
[7] 0.99001994 0.30737332 0.09461909 0.15720154</code></pre>
<p>Note that since a wide variety of NIMBLE models can be compiled, NIMBLE should be generally useful for developing production R code. Have a look at the <a href="https://cross.ucsc.edu/wp-content/uploads/2017/09/paciorek-cross17.pdf">presentation</a> by Christopher Paciorek for a nice overview of NIMBLE’s compilation process.</p>
<div class="figure">
<img src="/post/2018-07-03-Rickert-NIMBLE_files/NIMBLE.png" />
</div>
<p>Next, the default NIMBLE MCMC algorithm is used to generate posterior samples from the distributions for the model parameters <code>alpha</code>, <code>beta</code>, <code>theta</code> and <code>lambda</code>, along with summary statistics and the value of Wantanabi’s <a href="https://www.rdocumentation.org/packages/LaplacesDemon/versions/16.1.0/topics/WAIC">WAIC</a> statistic.</p>
<pre class="r"><code>mcmc.out <- nimbleMCMC(code = pumpCode, constants = pumpConsts,
data = pumpData, inits = pumpInits,
monitors=c("alpha","beta","theta","lambda"),
nchains = 2, niter = 10000,
summary = TRUE, WAIC = TRUE)</code></pre>

<h3>Monte Carlo Expectation Analysis</h3>
<p>To illustrate that NIMBLE is more than just an MCMC engine, the manual example uses NIMBLE’s built-in Monte Carlo Expectation algorithm to maximize the marginal likelihood for <code>alpha</code> and <code>beta</code>. The first step is to set up “box constraints” for the model. Then, the <code>buildMCEM()</code> function is used to construct an MCEM algorithm from a NIMBLE model.</p>
<pre class="r"><code>pump2 <- pump$newModel()
box = list( list(c("alpha","beta"), c(0, Inf)))
pumpMCEM <- buildMCEM(model = pump2, latentNodes = "theta[1:10]", boxConstraints = box)</code></pre>
<p>This is how to run the Monte Carlo Expectation model. Note that the authors of the NIMBLE manual point out that these results are within 0.01 of the values obtained by George et al.</p>

<p>Like the tidyverse, NIBMLE is an ecosystem of DSLs. The <code>BUGS</code> language is extended and used as a DSL for formulation models. <code>nimbleFunctions</code> is a language for writing algorithms that may be used with both <code>BUGS</code> and R. But, unlike the tidyverse, the NIMBLE DSLs are not distributed across multiple packages, but instead wrapped up into the NIMBLE package code.</p>
<p>For more on the design an use of DSLs with R, have a look at the <a href="http://adv-r.had.co.nz/dsl.html">Chapter in Advanced R</a>, or Thomas Mailund’s new book, <a href="https://www.apress.com/gp/blog/all-blog-posts/domain-specific-languages-in-r/15742536">Domain-Specific Languages in R</a>.</p>

May 2018: “Top 40” New Packages
https://rviews.rstudio.com/2018/06/26/may-2018-top-40-new-packages/
Tue, 26 Jun 2018 00:00:00 +0000https://rviews.rstudio.com/2018/06/26/may-2018-top-40-new-packages/
<p>While looking over the 215 or so new packages that made it to CRAN in May, I was delighted to find several packages devoted to subjects a little bit out of the ordinary; for instance, <code>bioacoustics</code> analyzes audio recordings, <code>freegroup</code> looks at some abstract mathematics, <code>RQEntangle</code> computes quantum entanglement, <code>stemmatology</code> analyzes textual musical traditions, and <code>treedater</code> estimates clock rates for evolutionary models. I take this as evidence that R is expanding beyond its traditional strongholds of statistics and finance as people in other fields with serious analytic and computational requirements become familiar with the language. And, when I see a package from a philologist and scholar of “Ancient and Medieval Worlds”, I am persuaded to think that R is making a unique contribution to computational literacy.</p>
<p>Below are my “Top 40” package picks for May 2018, organized into the following categories: Computational Methods, Data, Data Science, Finance, Mathematics, Music, Science, Statistics, Time Series, Utilities and Visualization.</p>

<p>In a <a href="https://rviews.rstudio.com/2018/03/08/cran-package-metadata/">previous post</a>, I showed a very simple example of using the R function <code>tools::CRAN_package_db()</code> to analyze information about CRAN packages. <code>CRAN_package_db()</code> extracts the metadata CRAN stores on all of its 12,000 plus packages and arranges it into a “database”, actually a complicated data frame in which some columns have vectors or lists as entries.</p>
<p>It’s simple to run the function and it doesn’t take very long on my Mac Book Air.</p>
<pre class="r"><code>p_db <- tools::CRAN_package_db()</code></pre>

<p>So, having spent a little time leaning how vexing working with this data can be, I was delighted when I discovered Ioannis Kosmidis’ <code>cranly</code> package during my March “Top 40” review. <code>cranly</code> is a very impressive package, built along tidy principles, that is helpful for learning about individual packages, analyzing the structure of package and author relationships, and searching for packages.</p>
<pre class="r"><code>library(cranly)
library(tidyverse)</code></pre>
<pre><code>## ── Attaching packages ──────────────────────────────────────────────────── tidyverse 1.2.1 ──</code></pre>
<pre><code>## ✔ ggplot2 2.2.1 ✔ purrr 0.2.4
## ✔ tibble 1.4.2 ✔ dplyr 0.7.5
## ✔ tidyr 0.8.1 ✔ stringr 1.3.1
## ✔ readr 1.1.1 ✔ forcats 0.3.0</code></pre>
<pre><code>## ── Conflicts ─────────────────────────────────────────────────────── tidyverse_conflicts() ──
## ✖ dplyr::filter() masks stats::filter()
## ✖ dplyr::lag() masks stats::lag()</code></pre>
<p>The first really impressive feature is a “one button” clean function that does an amazing job of getting the data in shape to work with. In my preliminary work, I struggled just to get the author data clean. In the approach that I took, getting rid of text like [aut, cre] to get a count of authors took more regular expression work than I wanted to deal with. But <code>clean_CRAN_db</code> does a good job of cleaning up the whole database. Note that the helper function <code>clean_up_author</code> has a considerable number of hard-coded text strings that must have taken hours to get right.</p>
<pre class="r"><code>package_db <- clean_CRAN_db(p_db)</code></pre>
<p>Once you have the clean data, it is easy to run some pretty interesting analyses. This first example, straight out of the package vignette, builds the network of package relationships based on which packages import which, and then plots a summary for the top 20 most imported packages.</p>
<pre class="r"><code>package_network <- build_network(package_db)
package_summaries <- summary(package_network)
plot(package_summaries, according_to = "n_imported_by", top = 20)</code></pre>
<p><img src="/post/2018-05-30-exploring-r-packages_files/figure-html/unnamed-chunk-6-1.png" width="672" /></p>
<p>There is also a built-in function to compute the importance or relevance of a package using the <a href="http://www.math.cornell.edu/~mec/Winter2009/RalucaRemus/Lecture3/lecture3.html">page rank</a> algorithm.</p>
<pre class="r"><code>plot(package_summaries, according_to = "page_rank", top = 20)</code></pre>
<p><img src="/post/2018-05-30-exploring-r-packages_files/figure-html/unnamed-chunk-7-1.png" width="672" /></p>
<p>The <code>build_network</code> function also offers the opportunity to investigate the collaboration of package authors by building a network from the authors’ perspective.</p>
<pre class="r"><code>author_network <- build_network(object = package_db, perspective = "author")</code></pre>
<p>Here, we look at J.J. Allaire’s network. <code>exact = FALSE</code> means that the algorithm is not using exact matching.</p>
<pre class="r"><code>plot(author_network, author = "JJ Allaire", exact = FALSE)</code></pre>

<p>It is also possible to study individual packages. Here, I plot the very simple dependency tree for the time series package <code>xts</code>. There is a very good argument to be made that the simpler the dependency tree the more stable and reliable the package.</p>
<pre class="r"><code>xts_tree <- build_dependence_tree(package_network, "xts")

<p>As a final example, consider how the <code>package_with()</code> function might be used to search for Bayesian packages by searching for packages with “Bayes” or “MCMC” in the description. I don’t believe that this exhausts the possibilities of <code>cranly</code>, but it should be clear that the package is a very useful tool for looking into the mysteries of CRAN.</p>

April 2018: “Top 40” New Packages
https://rviews.rstudio.com/2018/05/24/april-2018-top-40-new-packages/
Thu, 24 May 2018 00:00:00 +0000https://rviews.rstudio.com/2018/05/24/april-2018-top-40-new-packages/
<p>Below are my “Top 40” picks from the approximately 212 new packages that made it to CRAN in April. They are organized into ten categories: Computational Methods, Data, Data Science, Machine Learning, Music, Science, Statistics, Time Series, Utilities, and Visualizations.</p>
<h3 id="computational-methods">Computational Methods</h3>
<p><a href="https://cran.r-project.org/package=diffeqr">diffeqr</a> v0.1.1: Provides an interface to <a href="http://docs.juliadiffeq.org/latest/">DifferentialEquations.jl</a> which offers high performance methods for solving ordinary differential equations (ODE), stochastic differential equations (SDE), delay differential equations (DDE), differential-algebraic equations (DAE), and more. There are vignettes for solving <a href="https://cran.r-project.org/web/packages/diffeqr/vignettes/dae.html">differential algebraic equations</a>, <a href="https://cran.r-project.org/web/packages/diffeqr/vignettes/dde.html">delay differential equations</a>, <a href="https://cran.r-project.org/web/packages/diffeqr/vignettes/ode.html">ordinary differential equations</a>, and <a href="https://cran.r-project.org/web/packages/diffeqr/vignettes/sde.html">stochastic differential equations</a>.</p>

March 2018: "Top 40" New Package Picks
https://rviews.rstudio.com/2018/04/30/march-2018-top-40-new-package-picks/
Mon, 30 Apr 2018 00:00:00 +0000https://rviews.rstudio.com/2018/04/30/march-2018-top-40-new-package-picks/
<p>By my count, just over 200 new packages made it to CRAN and stuck during March. The trend for specialized, and sometimes downright esoteric science packages continues. I counted 40 new packages in this class. Most, but not all of these, are focused on bio-science applications. For example, the <a href="https://cran.r-project.org/package=foreSIGHT">foreSIGHT</a> package profiled below focuses on climate science. I was also pleased to see two new packages (not from RStudio) in the Data Science category, <a href="https://cran.r-project.org/package=h2o4gpu">h2o4gpu</a> and <a href="https://cran.r-project.org/package=onnx">onnx</a>, built on the <a href="https://cran.r-project.org/package=reticulate">reticulate</a> package for interfacing with <code>Python</code>.
