问题
I'd like to use R major mode for another file extension in emacs (for an unsupported language with syntax similar to R).
How do I force emacs to change the major mode for a buffer I'm editing? How do I change my .emacs to permanently associate a major mode with a particular file extension?

This should work:
(add-to-list 'auto-mode-alist '("\\.rr" . R-mode))
