Thanks for the clarification and that answers the question. This was a specific header argument for R. Perhaps the manual could link to this page? - http://orgmode.org/worg/org-contrib/babel/languages.html Maybe with a diddy: "Some languages feature their own unique header arguments. The above document only universal, system wide Babel header arguments and one should consult the specific language page on Worg for additional features." Just a thought.
