Dan,

the Windows build of R has no back-end choices, so the error essentially comes from a system call which means that Windows simply cannot provide the resources. Have you tried let's say Cairo alternative on the same machine? [If you want to test it, please use install.packages("Cairo",,"http://rforge.net") ] That doesn't depend on the OS resources, only on RAM so it may be in theory more scalable.

Cheers,
Simon
