Graphics on MacOSX

Ist there a possibility on MacOSX to import Graphics into MSOffice
Applications and resize them there without decreased quality? When I import
via copy&paste I get low quality bitmaps and via import pictures (pdf) it is
all the same. In the Windows versions of R there is the convienient way to
use metafile format which can easily be resized in ppt and word. What is the
equivalent way on MacOSX?
Thanks, Dirk.

This is a big issue for me, causing many days of angst. I finally 
stumbled on the following solution. I create a device save an image 
with postscript(). I then open it in Adobe Acrobat, select the area I 
want, enlarge to at least 400%, then copy, then paste into PowerPoint 
or Word. Alternatively, you can simply save a graphics image through 
the gui and it saves it as pdf. Then go through the steps of selecting, 
enlarging and copying in Acrobat. I am guessing real graphics programs 
would work as well (Photoshop or Illustrator), but I don't have those.

Dear Dirk and Hank,

You could try creating a PNG with bitmap() using a high resolution, 
e.g.,

bitmap("test.png", type = "png256", res = 1200)
plot(1:10, rnorm(10))
dev.off()

Preview can read the resulting PNG file just fine and the Windows 
version of Office can insert PNGs, displays them well, and allows 
resizing. (I don't have an OS X version of Office so can't test that 
the OS X version would handle the PNGs equally well but I would have to 
assume it does.)

bitmap() requires Ghostscript which I have installed on my system in 
/usr/local/bin. I'm not sure whether Ghostscript came with OS X or if I 
installed it myself but it's freely available.

Hope this helps,

Stephen
