Re: org-babel R, export, and :result value raw

[Eric Schulte <schulte.eric@gmail.com>]

Hi Christophe,

This issue of result wrappers (e.g., raw org html) not playing well with
result types (e.g., vector, scalar) came up a couple of months ago on
this mailing list and was not resolved.

I've just pushed up a change which should fix this problem, along with
an R-specific fix so that R respects the "scalar" and "verbatim"
:results header arguments so that the following now works.

#+begin_src R :results raw scalar
"[[file:bar.png]]"
#+end_src
