I have found graphics saved with the png() driver to be of sufficient quality to place in PowerPoint on the Mac, and use for presentations.
png() does require a running X windows server (which I don't consider to be a problem, but many Mac users do), but I would expect the GDD() driver to generate good quality as well. -Don At 12:31 PM -0400 5/30/07, Simon Urbanek wrote: >Guangjie, > >On May 30, 2007, at 12:00 PM, Guangjie Chen wrote: > >> I have been using R for Windows for a while, but i want to change >> to R for Mac.
