I asked about this ':results raw' limitation before and was told to RTFM
;)
(although its not really on the page where I would look for it:
http://orgmode.org/manual/results.html).
You could look-up that thread in the mailing-list for some tips, and/or
use this on a temporary buffer-copy just before you want to act on the
raw results:
#+BEGIN_SRC emacs-lisp :results none
(defvar tj/fixed-width-to-raw-langs '("R")
"List of Babel langs for `tj/fixed-width-to-raw-results'.")
(defun tj/fixed-width-to-raw-results ()
"Call `org-toggle-fixed-width' on ':results pp'."
(org-babel-map-src-blocks nil
(and (member lang tj/toggle-fixed-width-src-block-langs)
(member "pp" (split-string header-args " " t))
(save-excursion
(goto-char (org-babel-where-is-src-block-result))
(forward-line)
(while (org-in-fixed-width-region-p)
(org-toggle-fixed-width)
(forward-line))))))
#+END_SRC
#+begin_src R :results pp replace
c("** New header2", "[[./graph1.pdf]]", "", "** and second header", "and some
text" )
#+end_src
#+results:
: ** New header2
: [[./graph1.pdf]]
:
: ** and second header
: and some text
