You don't specify which version of R you are running, but it looks
like it's lower than 2.14 which is the current release version.
Please update to R-2.14. Make sure ImageMagick is installed and that
its directory has indeed been added to the PATH.

If you still have problems, please include the output of
sessionInfo()
in your reply.

Thanks,
Dan
