[R] Setting .Rprofile for RStudio on a Windows 7 x64bit

I think the site-specific R profile should be, using R syntax
   file.path(R.home("etc"), "Rprofile.site") # no dot before the capital R
The personal R profile will be
   file.path(Sys.getenv("HOME"), ".Rprofile") # there is a dot before capital R
but if a local R profile,
   file.path(getwd(), ".Rprofile") # there is a dot before capital R
exists it will be used and the one in HOME will not be.  (getwd() should
be the startup directory.)
