You can do stuff like this using babel and some R code.

Here is a start:

--8<---------------cut here---------------start------------->8---
#+NAME: my-block
#+BEGIN_SRC R :eval no
ls()
a <- 1
sqrt(a+2)
ls()
#+END_SRC


#+BEGIN_SRC R :session :noweb yes :results value raw :wrap example
 	capture.output(
             source(textConnection("
   <<my-block>>
   "),
   echo=T,print=T))
#+END_SRC

#+RESULTS:
#+BEGIN_example

> ls()
[1] "a"

> a <- 1

> sqrt(a+2)
[1] 1.732051

> ls()
[1] "a"
#+END_example


--8<---------------cut here---------------end--------------->8---

I suppose you would want `:exports results'.

Best,
Chuck
