ESS is the mechanism by which org-mode interfaces with a running R process.
And I think I left out a crucial piece of information in my first message: I
run R in a session buffer, my full .org file looks like this:
###################################
#+TITLE: Test doc
#+AUTHOR: Ken Williams
#+BABEL: :session *Rt*
* My Header
Some code:
#+begin_src R
ddply(x,
#+end_src
###################################
With that change, is the hang reproducible?

I could *SWEAR* I had tried C-g to abort the running R command (and C-c C-c,
and C-c C-g, and about a dozen other things), but couldn't get it to react.
Now it aborts as desired. I must have not actually tried a simple C-g. I can
never remember which keys abort which aspect of operation.
When I'm armed with that C-g, the hang is a much smaller issue!
