A package for the analysis of frequency data, ANOFA, has been released on CRAN. With this package, it is now possible to analyze frequencies following the logic of ANOVAs, by examining interaction effects and main effects, or explore simple effects (with expected marginal frequencies) or analyze one-degree-of-freedom orthogonal contrasts. If you were planning on doing a chi-square test on a contingency table, think twice and read Sharpe (2015) https://*doi*.org/10.7275/tbfa-x148 . Then you will consider running an ANOFA . Examples are given in Laurencelle & Cousineau (2023) https://doi.org/10.20982/tqmp.19.2.p173 Also, a simple function for plotting the frequencies along with confidence intervals is shipped with the package.
