PDF is actually a very good format supporting both bitmap (cf PhotoShop) and vector graphics (cf Illustrator) - it's even better than old PostScript, because it supports transparency and other cool things. Mac OS X actually uses PDF as its main display format. In fact PS used to be the standard for publishing and nowadays PDF is replacing that role. As a Mac user you're in the fortunate position of having many good PDF tools at your fingertips (in contrast to the Win folks :P).
well, let me say that the PDF file saved via R menus on mac, makes a copy of the current graphic device (quartz) on the R pdf() device. It's order of magnitude smaller that what you get by using quartz (but don't ask me why, I simply don't have to check at the moment). stefano
There's not much we can do about the Quartz file sizes---Quartz doesn't do much compression and includes a lot of redundant information---either for safety reasons or size/speed tradeoff. There are a couple of post-processing tools that can shrink Quartz PDFs, but who knows. Rumor has it that Tiger's PDFKit may help with that.
