Send line to R process from babel block?

[John Hendy <jw.hendy@gmail.com>]

If one opens file.R and does =C-RET= on a line, it sends it to the
current ESS R process running (or starts a new process and then sends
the line).

Is this possible from babel blocks? I would find this extremely
helpful when troubleshooting in order to run lines of code up to my
problem spot vs. my current practice of copying, switching buffers,
then yanking into the R session buffer.

Is this already possible? I looked around at some of the completions
for =M-x org-babel-*=, but didn't see anything promising.


Thanks,
John
