[R] Loading functions in R

[Matthew Keller]

Hi Jeff,

The way I do this is to place all the options that I want, along with
functions I've written that I always want available, into the
"Rprofile.site" file. R always loads this file upon startup. That file
is located in the etc/ folder. E.g., on my computer, it is at:
C:\Program Files\R\R-2.2.1\etc\Rprofile.site . This is explained in
section 10.8 of the R-intro.pdf manual that comes with R.

If you only want the functions available sometimes, then use Christos'
suggestions.
