August 2021: "Top 40" New CRAN Packages

This is a companion discussion topic for the original entry at https://rviews.rstudio.com/2021/09/27/august-2021-top-40-new-cran-packages


One hundred sixty new packages covering a wide array of topics made it to CRAN in August. I thought I would emphasize the breadth of topics by expanding the number of categories organizing my “Top 40” selections beyond core categories that appear month after month. Here are my picks in fourteen categories: Archaeology, Computational Methods, Data, Education, Finance, Forestry, Genomics, Machine Learning, Medicine, Science, Statistics, Time Series, Utilities, and Visualization. Based on informal impressions formed over the last several months, I believe a new category combining applications in forestry, animal populations, climate change could become a regular core category.

Archaeology
