Likely it's not really in your path. Use Sys.getenv("PATH") to see what
R sees as your path. It certainly won't look like what you just posted:
those % variables will be expanded, for instance.
If C:\Program Files\ImageMagick-6.5.6-Q16 is on your real path, then go
to that folder, and make sure the executable "convert.exe" is there.
That's what rgl is looking for.
