Error in install.packages : unable to create ‘C:/Users/????????/Documents/R/win-library/4.0’

If you will forgive a possibly foolish question, have you installed Rtools40?

Also, you need to run RStudio as administrator to be able to install in the system level package library.

And, you can't use a personal package library located in a path with non-ASCII characters.
