Even if Heather is using a suboptimal way to export graphics, it still shouldn't crash R though. Heather, if this is in any way reproducible, please include the code that causes the crash. Also, run R from the terminal with "--vanilla" option when reproducing if possible (to ensure a clean session), and include the output after the crash. (E.g., "Segmentation fault", or whatever it may be.)
