 Replying to [comment:10 annakrat]:
 > The zipcodes are already clumped, or?

 It doesn't look like: zipcodes has 13 distinct cat values. r.clump
 generates 16 clumps and r.clump -d generates 14 clumps.

 Maybe zipcodes isn't a good example map for r.reclass.area in the first
 place, because when following the man page: some area of zip code 27606 is
 lost during the clumping (without the innocent user being aware of this
 risk, I would assume).
 {{{
 |27606|RALEIGH. . . . . . . . . .|  6626.420| # Size in ha in original
 zipcodes map
 |27606|RALEIGH. . . . . . . . . .|  6626.410| # 1 px = 100m2 = 0.01 ha
 lost in zipcodes_larger2000ha
 }}}
