[GRASS-user] weighted mean

Hi,
does anyone here know if there is a command in Grass that calculates the weighted mean (on areas) of values in a coloumn in the attribute table of a vector layer?

Since I need to execute this command for several vector layers, would it be possible to automatically create a new tablet filled with the calculated values?

I thank you in advance for your reply.
Best regards.

v.univar calculates for areas the mean from values in a column in the
attribute table weighted by the size of each area. Is this what you
are looking for?
