Eeks. Is the fact that I learned emacs only for org-mode showing. I
don't even know how to =(info "(elisp) Edebug")= -- do I put an =M-x=
in front of that? =M-x info= seems to bring me to a help page for
info!

Anyway... I just googled edebug and it says about the same as you did
(except for appending "eval-defun with a prefix argument" onto =C-u
C-M-x=.
- http://www.gnu.org/software/emacs/manual/html_node/elisp/Using-Edebug.html

Anyway:
- Visited ob-R.el in emacs
- Found org-babel-R-evaluate-external-process
- Put the cursor on the line =(defun org-babel-R-evaluate-external-process=
- Did =M-x C-M-x= and the minibuffer echoed the name of the function
- Visited my file, test.org and did =C-c C-c= on the R babel block
- Nothing different occurred; I just got "The system cannot find the
path specified"

I tried the above again with regular 'ol org-babel-R-evaluate just in
case and had the same results.

I'm clearly goofing something but have no idea what it is.
