Thanks for the pointer. It is an issue with the graphics device being used.
Using cairo and family (instead of fonts) works for me:
#+BEGIN_SRC R :results output graphics :exports results :file filename.png
:width 1200 :height 700 :type cairo :family serif
<<R code here to produce a graph>>
#+END_SRC
