maybe Nikos could comment.

Note that with the R-grass bridge you can use any of the many R
statistical methods + functions.

ps- patch added in the trac system to allow i.rbg2his to work
with 11-bit data (I fixed the truncation to 255 you saw before),
but d.his and i.his2rgb are still 8-bit only for now. Waiting
on word that I'm on the right track before moving onto the other
modules.
