Oh, sorry: edebug is described in

(info "(elisp) Edebug")

The basics: visit ob-R.el, go to the org-babel-R-evaluate-external-process
definition and press C-u C-M-x. Then do whatever you were doing to get the
problem. It should stop at the function and you can single-step by pressing
SPACE. At strategic points, you can evaluate things with "e".

If you mess it up (and you probably will a few times), no problem: just try
again. And be patient!

Good luck,
Nick
