There isn't (at least that I can recall).  Actually, the "preferred"
(at least by me) method of using ESS is to keep a buffer of the
commands, running in R-mode (or similar), and just dump and edit
line-by-line, using the send-current-line command (it has a real name
which escapes me now).  This allows you to avoid including typos in
your history, which sometimes is nice.

Then, write out the actual process buffer as a "running" transcript,
save your command file as the "history", etc...

(The current preferred philosophy states that "Emacs buffer contents
and file contents are the truth, and the .RData/.Data/_Data contents
are temporary manifestations of the truth, to be recreated from the
buffer/file contents as needed".  Like all philosophies, you are free
to roll your own).
