OK, will do. Still the question remains whether this is a bug, an error 
in the manual page (i.e., threshold values are not in mapping units, but 
in meters like for the rmarea) , or I am doing something wrong (note 
that it seems to work fine if one assumed threshold values have to be in 
meters). If a bug or error in the manual page, I can create a ticket.
