[R] Are there any packages that can process images other than pixelmap (i.e. pnm)?

[Arthur Roberts]

Hi, all,

I am having trouble getting R to take pnm images via mogrify

i.e.

mogrify -resize 320x217 -format pnm *.png

However R via pixmap says that it can't read the file.  If you have  
any ideas like a package that can read jpeg files, etc., I would  
appreciate it.

Best wishes,
