I tried this

 	pandoc -f markdown -t org input-file.Rmd -o output-file.org

then I opened `output-file.org' and put this src block at the very top:

#+BEGIN_SRC emacs-lisp :results silent
   (replace-regexp "^=[{]r \\([^}]*\\)[}]\\(.*\\)=$"
 		  "#+name: \\1
   ,#+begin_src R
   \\2
   ,#+end_src")

#+END_SRC

When I execute that code block, all the converted code chunks become src 
blocks.

This isn't perfect as chunk options are appended to the `#+NAME:...' line, 
but if you want to play with the regexp's you can probably get it to pick 
those out and put them on a separate line. Or just write another src block 
with another `replace-regexp' to fix those lines.

With a little effort you can write a command file for `sed' to do what the 
code block above does and then pipe the pandoc output to that command like 
this:

: pandoc -f markdown -t org input-file.Rmd | \
: sed -f convert-chunks > output-file.org

and you have an org document ready (or almost ready) to go.


HTH,
