R help - Jul 2009 - reading jpeg images?

Can someone advise me what the most sensible way is to read jpeg images?

   For our work with image analysis and eye-tracking we have been using the
   rimage package, on both Macs and Windows PCs. But while setting up a new
   Windows machine yesterday, I see that rimage is regarded as orphaned, and no
   Windows binary is available. I eventually found an old zip file for the
   package,  so  I am not stuck, but I wonder what the right way is to go
   forward. I did find the readimages package, but it also seemed problematic
   to install on both Windows on Mac, requiring extra software that it was
   itself unclear how to install.

   Is there some simpler solution I should be looking at?

   Are jpeg files so probematic I should be converting them to some other
   format and using a different package to read that?


   Thanks

I found the 'biOps' package for "Image and data analysis"
quite helpful.
(I did some astronomical investigations with it --- counting galaxies in
 a Hubble picture---and I do recommend this package.)

Under Windows you have to unpack the 'libjpeg' and 'libtiff'
libraries
beforehand somewhere in your path.
See <finzi.psych.upenn.edu/Rhelp08/2009-April/194630.html> for a link
to download all necessary libraries as a zip-file.

If this link to RapidShare does not work anymore, I think I still have
that file somewhere and could send it to you by e-mail.

Regards
Hans Werner
