Hmm, since this thread seems to perpetuate ..
let me take the opportunity to explain how enormously nicely (:-)
this is achieved in ESS (Emacs Speaks Statistics):

1) ?plot opens a separate emacs buffer with the help page.
2)       and emacs gains a separate "ESS-help" menu.

3) From that menu you can learn that you can very quickly move
   around in the help buffer using "n"(ext) and "p"(revious) or
   skip to a section via  "s <letter>."
   Now the most used keystroke in ESS help buffers I use is 
   "s e" := "[S]kip to the [E]xamples section".

4) Inside the examples section, 'l' (single lowercase "L" for [L]ine)
   sends single lines to the running *R* process, or 'r' sends a
   whole [R]egion (that you typically have marked with the mouse).

Since it seems that there are ESS users who don't know about
this feature, I'm also CCing this to ESS-help.

(and yes, I could go on: You can also send code from the
 examples when *editing* the *.Rd  (R help) files ...)
