Thanks to everyone for the help and advice! It turns out that my problem was using $HOME in the .First function in Rprofile.site. Since $HOME is a user specific variable, it seems to have crashed when running from the $R_HOME/etc/ directory. I added the other .Rprofile files without deletng the Rprofile.site file, so it never got to them. When I went back and deleted Rprofile.site, the .Rprofile files in my home directory and working directory work fine.

Thanks!
