## DESCRIPTION

Makes each cell value a function of the attribute values assigned to the vector points or centroids around it, and stores new cell values in an output raster map layer.

## EXAMPLE

Count the number of schools for a given grid (North Carolina sample dataset):

    g.region vector=schools_wake res=100 -p -a
    v.neighbors input=schools_wake output=schools_wake_3000m method=count size=3000

    d.mon wx0
    d.rast schools_wake_3000m
    d.vect schools_wake

The result gives for each grid cell the number of points (here: schools) not farther than 1500 meter away (half of the given size value) from the respective cell center.
