Your questions is essentially FAQ 7.19.  

In non-interactive mode, R simply has no X11 device. You need xvfb or other
solutions.  A relatively new option is the Cairo device which IIRC does
not need X11 and a display variable.

There are other options, including embedding R or running Rserve, but they
are all little more involved.  

Cheers, Dirk
