R.COIN and percentage

[Cathy Ciret]

Hello,
I'm not sure you are the right people to ask this question. If you're
not, I apologize for the inconvenience. 
I'm a GRASS user, and I'd like to find out something without having 
to subscribe to the GRASS-users mailing list.

1. I'm using r.coin after putting a mask on the ocean. If  choose
"cell" it's fine, if I choose "p" as "percent cover of region",
GRASS seems to ignore the mask and give me the percentage of ,say,
tropical rainforest , expressed as percentage of the entire planet,
and not percentage of land area only, even if the ocean is masked.
Am I doing something wrong, or the mask does not applied to
this unit?

2. Is there a HomePage on the Web about GRASS?

I appreciate your help.
Regards
Catherine Ciret
