[R] Troubles installing Rcmdr on Mac

[John Fox]

Dear Stephane and Eberhard,

As an addendum to my previous response, I uninstalled the Rcmdr package 
and all of its direct and indirect dependencies and then reinstalled the 
package -- on a macOS 11.1 system running R 4.0.3 with all other 
packages up-to-date.

I then reinstalled the Rcmdr and dependencies via the command 
install.packages("Rcmdr"), and responded "no" when asked whether to 
install some packages from source (perhaps this is the explanation for 
the problem, if your students responded "yes" without having Xcode 
installed).

Following these steps, everything (still) works fine. I therefore can't 
duplicate your students' problem, which makes it hard to suggest how to 
fix it, without having some additional details.

Best,
  John
