marginscommand for calculating marginal (or partial) effects. There is an introduction, a vignette on the Technical Implementation Details, and a comparison with the Stata Command.
mlrMBO v1.0.0: Provides a toolbox for Bayesian, model-based optimization. There is an introduction and vignettes for Mixed Space Optimization, Noisy Optimization, and Parallelization.
MonteCarlo v1.0.0: Simplifies Monte Carlo simulation studies by providing functions that automatically set up loops to run over parameter grids, parallelize the computations, and generate output in LaTeX tables. The vignette shows how to use it.
RankingProject v0.1.1: Provides functions to generate plots and tables for comparing independently sampled populations. There is an introduction and a vignette that reproduces the figures from “A Primer on Visualizations for Comparing Populations, Including the Issue of Overlapping Confidence Intervals” by Wright, Klein, and Wieczorek (2017, The American Statistician, in press).
rjmcmc v0.2.2: Provides functions to perform reversible-jump MCMC with the restriction introduced by Barker & Link. The vignette shows how to calculate posterior probabilities from the MCMC output.
collapsibleTree v0.1.4: Provides functions to build interactive Reingold-Tilford tree diagrams created using D3.js, where every node can be expanded and collapsed by clicking on it. There are some examples on the GitHub site.
cronR v0.3.0: Allows users to schedule R scripts and processes on Unix/Linux systems, while taskscheduleR allows the same from Windows. See the cronR vignette and the taskscheduleR vignette.
doctr v0.2.0: Provides tools to help check the consistency and quality of a dataset. There are vignettes for Comparing Tables, Dataset Diagnostics, and EDA Automation.
geojsonR v1.0.1: Provides functions to process GeoJson objects. The vignette gives the details.
ggedit v0.2.1: Provides an interactive layer and theme aesthetic editor for ggplot2. The ggedit gitbook explains how to use it.
implyr v0.1.0: Provides a SQL backend to dplyr for Apache Impala.
officer v0.1.0: Provides functions to manipulate Microsoft Word and Microsoft Powerpoint documents. This is a companion package to flextable.
flextable v.1.0: Includes functions to create tables in Word, PowerPoint, and HTML documents. There is an overview, and vignettes for explaining objects and table layout.
pivottabler v0.1.0: Allows users to create complex pivot tables and pivot tables with irregular layouts in R. There are multiple vignettes, including an introduction, a styling guide, a Shiny example and explanations of calculations and data groups.
