Christophe provided the org solution a) and obviously that's the way to go
(maybe one of you could provide a patch to change the default value of
org-export-latex-minted-langs to add the R setting?)
For completeness, and of theoretical interest only, here's how to do b).
o Find the directory where pygments is installed. I just started python
imported pygments and asked for help:
,----
| $ python
| Python 2.7.1+ (r271:86832, Apr 11 2011, 18:13:53)
| [GCC 4.5.2] on linux2
| Type "help", "copyright", "credits" or "license" for more information.
| >>> import pygments
| >>> help(pygments)
| Help on package pygments:

| NAME
| pygments

| FILE
| /usr/lib/python2.7/dist-packages/pygments/__init__.py
| ...
`----
o cd /path/to/pygments/lexers, edit the file math.py (you probably have
to be root) and add the 'R' alias for 'S':
,----
| ...
| name = 'S'
| aliases = ['splus', 's', 'r', 'R']
| filenames = ['*.S', '*.R']
| mimetypes = ['text/S-plus', 'text/S', 'text/R']
| ...
`----
o run (as root) the _mapping.py script to regenerate stuff:
,----
| $ sudo python _mapping.py
