Yah, but what if I need to write a package in R that reads these images?
too much manual trouble to use outside software. It's especially infeasible
these become a routine task with many images.
I think that here may be a place to make an improvement to R.
I, for one, can certainly appreciate the use of such reader functions. Are
there any one else
who felt the same way?

The pixmap package has functions for reading pnm (portable anymap) files,
but you still need an outside software to convert (like ImageMagick).
