Should be "$HOME/.Rprofile" for user-level default setting and
will be hidden by Finder. It's not something you're going to be
changing daily anyway and can be modified using TextWrangler's
'Open Hidden..." menu option by non-Terminal users.

This is not platform-specific and is described in Appendix B of
'Introduction to R' (pg 85 of R-intro.pdf).

I keep .First and .Last and a couple functions that pose as
typing shortcuts in ".Rprofile". Anything else I source an
external file..

Create a subdirectory under "~/Library/R" and store functions
there if nowhere else makes sense.
