[R] R commander (Rcmdr) won't start [SOLVED]

[Fox, John]

Dear Gabriele,

I'm glad that you were able to solve your problem. I spent a bit of time today updating my R from 3.6.0 to 3.6.1 and updating all R packages on Ubuntu, and, for what is now an obvious reason, I was unable to duplicate the problem.

Saving the .Rhistory file is benign but saving the R workspace at the end of a session in .RData can be problematic, and not just for the Rcmdr. You'll notice that while R makes saving the workspace the default (presumably to avoid inadvertent data loss, and in my opinion not a good default choice), the Rcmdr doesn't offer to save the R workspace when you select "File > Exit > From Commander and R" from the Rcmdr menus.

Best,
 John
