The Ranking Project: Visualizations for Comparing Populations

Description

Functions to generate plots and tables for comparing independently-sampled populations. Companion package to "A Primer on Visualizations for Comparing Populations, Including the Issue of Overlapping Confidence Intervals" by Wright, Klein, and Wieczorek (2019) <DOI:10.1080/00031305.2017.1392359> and "A Joint Confidence Region for an Overall Ranking of Populations" by Klein, Wright, and Wieczorek (2020) <DOI:10.1111/rssc.12402>. See the Intro vignette (html) for an overview and examples: vignette("intro", package = "RankingProject"). See the Primer vignette (pdf) for code which replicates the main figures from the 2019 article: vignette("primer", package = "RankingProject"). See the Joint vignette (pdf) for code which replicates the main figures from the 2020 article: vignette("joint", package = "RankingProject").

Details

The "comparison" plots are based on figures and S code from Almond et al. (2000). The present package does not contain a direct modification of their S code, but draws inspiration from it. Their script was originally hosted at Statlib at http://stat.cmu.edu/S/comprB and may still be found at Statlib mirrors such as http://ftp.uni-bayreuth.de/math/statlib/S/comprB.

The code for the "columns" plots is directly based on R's stats::heatmap() function, with minor modifications to remove dendrograms and allow the heatmap to be placed inside a larger layout().
