[R-SIG-Mac] rlang and the new R version 4.1.0

Tue May 25 22:28:20 CEST 2021

When R4.0 came out,  someone on R-Bloggers post a very nice to automate updating your packages from R3.6.  I just used it to do my update from R4.0 to R4.1 - it works perfectly.  I would include the script here,  but since I don't have the exact reference I don't like posting someone else's script without appropriate credit.  Do a search and you should be able to find the entry.

I would best recommend removing (or re-naming) ~/Library/R before installation to make sure you don't have incompatible old packages. Also don't forget to re-start R.
