Yes, I believe that's set up properly, because I can do "C-c C-c" and it
knows how to run my R sections and return the correct values.  Also, when I
"describe org-babel-load-languages", I see:

org-babel-load-languages is a variable defined in `org.el'.
Its value is ((emacs-lisp . t)
 (sh . t)
 (R . t)
 (perl . t))

I'm grasping at straws too, not knowing my way around the elisp code very
well. =)
