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.
