[R] PPM to BMP converter

[Jan van der Laan]

I don't know if any R-packages exist that can do this, but you could  
install imagemagick (http://www.imagemagick.org), which provides  
command line tools for image manipulation and conversion, and call  
these from R using system. Something like:

system("convert yourimage.ppm yourimage.bmp")

HTH,

Jan
