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 `---- Nick
