Have you tried using org mode, and org-babel?  You can either process
the whole buffer, or interactively run chunks and send them e.g. to an
*ESS* session that you can then interact with.

(What I don't like about org-babel is that it seems overly complicated,
compared to the straightforward markup of Sweave.)
