Mathieu,
   Most of the FRAGSTATS metrics are conceptually quite tractable.  I 
don't think it would take very many days of programming to reproduce 
FRAGSTATS in R.  Less so if the task were shared among contributors.

The raster package is a real aid in this regard.  It makes a lot of 
things quite straightforward.

The question is, though, is this worthwhile, given that FRAGSTATS 
already does the job more than adequately?  Where R comes in, I guess, 
is in cases where things need to be customized.
