sweave tables as images?

The hook function hook_pdfcrop() also works on PNG images, although
the function name is somehow misleading. The requirement is that you
have ImageMagick installed and the command 'convert' is in your PATH.

Thanks Yihui,

That's a great idea, and comes close to the mark, except that I have to
use png's in order to "Insert & Link" them as pictures in Word (and
hence make the doc both shareable and update when new figures are
generated).

thanks,
allie
