[GRASSLIST:5622] cat labels in mapcalc

[orkun]

Hello

I want to use cat labels instead of cat values in r.mapcalc
To create a new map from existing map's one category label
I tried this expression: 
r.mapcalc dene='if(@f28hey_cat=="R",1,0) # (R is cat label from f28hey_cat.)

Does anyone have an idea?

thanks in advance
