New CRAN package ggfourfold with initial version 0.1.0 #rstats https://cran.r-project.org/package=ggfourfold
CRAN: Package ggfourfold
Draws fourfold displays of 2 x 2 (x k) contingency tables as a 'ggplot2' layer, following Friendly (1994) <<a href="https://datavis.ca/papers/4fold/4fold.pdf" target="_top">https://datavis.ca/papers/4fold/4fold.pdf</a>> and Friendly and Meyer (2016) <<a href="https://doi.org/10.1201%2F9781315374413" target="_top">doi:10.1201/9781315374413</a>>. Cell frequencies are shown as quarter-circles or squares of proportional area, with confidence rings for the odds ratio and shading for the direction and strength of association. Stratified tables are shown with 'ggplot2' faceting and a corresponding 'ggplot2' theme is provided.
