In a recent post, I highlighted several new packages that arrived on CRAN in January that provided R users with access to data. In this post, I present additional selections for interesting January packages, organized into the categories Miscellaneous, Machine Learning, Statistics and Utilities.
rcss v1.2: Provides functions for Solving Control Problems with Linear State Dynamics.
stormwindmodel v0.1.0: Provides functions to calculate wind speeds for hurricanes and tropical storms in the North American Atlantic basin. One vignette describes the package and another shows how to use it.
- classifierplots v1.3.2: Provides functions to generate a grid of binary classifier and diagnostic plots with a single function call. See the README for details.
confSAM v0.1: Contains a function that computes estimates and confidence bounds for the false discovery proportion in a multiple testing environment. The vignette describes the theory and provides examples.
pdSpecEst v1.0.0: Implements a non-parametric, geometric wavelet method to estimate autocovariance matrix of a time series that preserves positive-definiteness of the estimator. This preserves the intrepretability of the estimate as a covariance matrix and helps with computational issues. The paper describes the theory and the vignette provides an example.
fst v0.7.2: Provides functions to read and write data frames at high speed, and compress data with type-optimized algorithms that allow random access of stored data frames.
manipulateWidget v0.5.1: Provides helper functions to add controls like sliders, pickers, checkboxes, etc. to interactive charts created with package htmlwidgets. The animated vignette will get you started.
msgtools v0.2.4: Provides utilities for error, warning, and other messages in R packages, including consistency checks across messages, spell-checking, and message translations for localization. See the vignette for examples.
padr v0.2.0: Provides functions to transform datetime data into a format ready for analysis, including aggregating data to a higher level interval (thicken) and imputing records where observations were absent (pad). There is an Introduction.
restfulr v0.0.8: Models a RESTful service as if it were a list.
sys v1.1: A replacement for base system2 with consistent behavior across platforms. Supports interruption, background tasks, and full control over STDOUT / STDERR binary or text streams. README provides some details.
unpivotr v0.1.0: Provides tools for converting data from complex or irregular layouts into a columnar structure. There is one vignette showing how to unpivot pivot tables from a spreadsheet, and another that shows how to work with multiple, similar tables.
