The following code does not produce image with serif fonts for me. It used to work earlier but it seems the behaviour has changed. Could anyone confirm.
#+BEGIN_SRC R :results output graphics :exports results :file filename.png :width 1200 :height 700 :fonts serif <<R code here to produce a graph>> #+END_SRC Org-version: Org-mode version 8.3beta (release_8.3beta-688-g44744b @ /Users/vikas/.emacs.d/src/org-mode/lisp/) Vikas
