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!
