This is a companion discussion topic for the original entry at https://rviews.rstudio.com/2021/03/19/february-2021-top-40-new-cran-packages

In February, two hundred forty-three new packages made it to CRAN, many of them very interesting and at least one entertaining. It was exceptionally difficult to pick the “Top 40”, but here they are, more or less, in eleven categories: Computational Methods, Data, Finance, Games, Genomics, Machine Learning, Mathematics, Medicine, Networks and Graphs, Statistics, Utilities, and Visualization. `iconr`

in the Networks and Graphs section is a package for doing computational archaeology, a relatively new field that I hope will dig R. I also hope that `sassy`

in the Statistics sections helps some statisticians find their way to R.
