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")

Dear all,
Several days ago, I posted How to write a bmp file pixel by
pixel. Instead of bmp, I succeeded in writing a PPM file by using
the pixmap package. Thanks for the hint generously provided by Uwe
Ligges.
Now I have a new question. How to convert a PPM file to BMP
file in R? I know I can do this in photoshop or by some other
softwares, but I think if I Can do this in R, that would be great!
Would anyone please give me any hints? just hints, I will dig it
out! Thanks a lot!
Yingqi
