Hi there

The default option for saving graphics from R (1.9.1) on my Mac is as a pdf file. If I open the file in Acrobat reader it looks really good and crisp, and is obviously saved as vector graphics, since I can zoom in as much as I like and it continues to look really nice. If I import it into MS Word (from office 2000), or Textedit, however, it imports it as a bitmap and unless I save it as a pretty big image and then shrink it in size by about three times after import it looks blurry and pixellated. The save it as a really big picture and shrink it option is bearable, but hardly elegant.

I'm trying to persuade some other people in my department that we should move to using R as a standard analysis package, and this is currently one strike against it - it's difficult to export decent-looking high-res graphics. If I want to persuade people to use R, I need to be able to give them an easy way to do this. There are some solutions like importing the text and then the graphics into acrobat, or installing ghostscript and trying it with the graphics as postscript, but obviously people will respond to this with 'why should I waste time and or money doing this when I can just cut and paste out of Excel/Statistica/Minitab'. I realise that this is arguably more of a problem with Word or Textedit, but does anyone know of a good easy solution to this that I can use as part of my program to evangelise my colleagues?

Thanks for any help
