Yet another approach is to create a postscript file on R for MacOSX and
convert to a windows metafile is:

> postscript("test.ps", width=5.0, height=6.0, paper="special")
> xyplot(1~1)
> dev.off

Then, using the "free"/included MacOSX bundled software, GraphicConverter,
convert the just-created postscript file to a WMF, (Windows Metafile
Graphics), format.  (This software has a batch conversion utility for
converting multiple graphs--just select the multiple files and off you go.)
Then, just import the newly converted .wmf files as you normally would into
MS Word/MS Powerpoint.  One (tiny) detail, though, is there is a bit of
cropping you may have to do as the paper size, at least on mine, defaulted
to letter, (which is the default).  The paper size did not restrict itself
to the 5"x6 " I specified earlier, but rather just the image size, (as
advertised in the documentation.)

However, the final printed product is as you wish--quality commensurate with
the Win32 version.


Good luck,
Charles

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
