Mikhail,
For vanilla Sweave, use the LaTeX style syntax (vs noweb style) to create an
Rtex file. Typing 'C-c C-e l' causes the following *.org to produce *.Rtex
which R CMD Sweave will turn to *.tex and R CMD pdflatex will turn into a
*.pdf.
Note this this will break ordinary R code export in latex, so be sure it
is not invoked when you want to go from *.org to *.pdf via 'C-c C-e d'
The trick is mainly to get the latex exporter to drop the verbatim wrapper.

* Retooling org-babel to accept Rtex
Run this subtree once to start or put these blocks in your =~/.emacs=
Either way, run the elisp in this subtree once to start a session
** Nullify =\begin{verbatim}= ... =\end{verbatim}=
Under standard latex export, the code blocks get wrapped in verbatim
environments. To Sweave the resulting code as =*.Rtex= it is necessary
to unplug this behavior. 'Advising'
=org-export-format-source-code-or-example= like this has the desired
effect on =R= src blocks , but leaves others alone.
#+begin_src emacs-lisp :exports code
(defadvice
org-export-format-source-code-or-example
(around no-verbatim (lang code &optional opts indent caption))
"dont wrap R code in verbatim"
( let
(( old-verb-wrap org-export-latex-verbatim-wrap))
(if (equal lang "R") (setq org-export-latex-verbatim-wrap nil))
ad-do-it
(setq org-export-latex-verbatim-wrap old-verb-wrap)))
(ad-activate 'org-export-format-source-code-or-example)
#+end_src
#+results:
: org-export-format-source-code-or-example
** after processing convert =*.tex= to =*.Rtex=
Adding the commands to run Sweave and pdflatex to this hook function
is left as an exercise...
#+begin_src emacs-lisp :results silent
(add-hook
'org-export-latex-after-save-hook
(lambda ()
(rename-file (buffer-file-name)
(concat (file-name-sans-extension
(buffer-file-name)) ".Rtex") t )
))
#+end_src
* SRC BLOCKS
Two simple examples
** R graphics
A simple scatterplot. Here we want the verbatim omitted:
\begin{Scode}{fig=T}
#+begin_src R :eval never :exports code :results raw
plot(rnorm(10))
#+end_src
\end{Scode}
** shell script
Here we want to execute the shell script and pass it to the =*.Rtex= file
#+begin_src sh :eval t :results output verbatim :exports both
ls | wc
#+end_src
