[R] When to use RProfile.site or .Rprofile

[Henrik Bengtsson]

Unless you're trying to provide your startup settings to multiple
users (typically only sysadms do this), stick with .Rprofile (in your
home directory).  There is no need to have one per working directory,
unless they differ, cf. ?Startup ["...a file called ‘.Rprofile’ is
searched for in the current directory or in the user's home directory
(in that order)."].  Also, RProfile.site resides where R is installed
(e.g. R_HOME/etc/).  Maintaining that one requires updates when the R
version/installation location is updated, whereas the one in you home
directory will always be found regardless of R version.

I currently use .First() in .Rprofile files placed in separate directories used for different RStudio projects.
