[R] Missing functions in package e1071(Win*)

[Prof Brian Ripley]

pnm functionality is only included if a pnm library is found, I have one,
but it does not work correctly with this package.  There is nothing wrong
with the archive, which is what you will get if you install e1071 on a
machine without pnm support.

Please do read the ReadMe there and/or the rw-FAQ.

Find a working pnm library and compile it yourself.
