This is a companion discussion topic for the original entry at https://rviews.rstudio.com/2021/12/21/november-2021-top-40-new-cran-packages
Two hundred eleven new packages made it to CRAN in November. Here are my “Top 40” picks in thirteen categories: Computational Methods, Data, Ecology, Finance, Genomics, Humanities, Machine Learning, Medicine, Networks, Statistics, Time Series, Utilities, and Visualization.
