I think I get your intention. You want the visual to look like it would if the src-edit buffer was opened in emacs as org.

I have two alternative approaches:

1) Add an export engine for "org" to ox-ravel[1]. This is a trivial customization of `org-ravel-engines' to add a '("org" . "engine='org'") element.  Then add a custom language engine[2] for rmarkdown or knitr.

The actions for the makefile would be a ravel export to generate *.Rmd, *.Rnw, or *.Rhtml files followed by rmarkdown::render or knitr::knit on the generated files.

2) Define this function:

#+begin_src emacs-lisp
  (defun org-exe-org ()
    (let ((org-confirm-babel-evaluate nil))
      (org-edit-src-code)
      (org-babel-execute-buffer)
      (org-edit-src-exit)))
#+end_src

In an org buffer with one or more org src blocks containing R src blocks:

eval this

 (org-babel-map-executables nil (org-exe-org))

Then export the buffer to pdf or html.

I haven't tested this much, but for the snippet below evaluating that line and exporting to html produces two framed blocks with R src blocks and the results displayed in each:

--8<---------------cut here---------------start------------->8---
#+begin_src org
  ,#+begin_src R
    print("abc")
  ,#+end_src
#+end_src


#+begin_src org
  ,#+begin_src R
    print("def")
  ,#+end_src
#+end_src
--8<---------------cut here---------------end--------------->8---

I expect doing this in batch mode will not be a challenge.

For pdf output the result is rather plain. Maybe there is some minted idiom that would help?

HTH,
Chuck

p.s. I am an `ess-intro' member, in case it helps to move the conversation to there.
