Following Anna's suggestion I had to find out that r.mode has to option
to handle NULL values, i.e. exclude it from calculation? I need to
aggregate rasters to polygons, with rasters covering only a small part
of the polygon. As I realized now r.mode returns NULL in such case.
Setting NULL with r.null null=9999 it will return 9999 for all of these.
Is there a solution to that problem?

Dear list
Is it possible to get the "mode" (most common occurring value) in
a polygon for discrete classes? It appears that v.rast.stats does
not have this option.
v.rast.stats uses r.univar and r.univar doesn't have mode implemented
(it's a TODO in manual). You can look at r.mode but it returns raster
map, not one number.

Thanks for a short feedback,
