I created a new vector of points (tmp4) using v.select, operator=within
0 areas built
0 isles built
Topology was built
Number of nodes: 577
Number of primitives: 577
Number of points: 577
All these points are inside the areas 1, 2, and 3 of the area vector "rami".
> Also output of v.info on the area vector
Area vector is "rami":
Type of map: vector (level: 2)
Number of points: 0 Number of centroids: 3
Number of lines: 0 Number of boundaries: 3
Number of areas: 3 Number of islands: 3
Map is 3D: No
Number of dblinks: 1
> and v.vect.stats after g.gisenv set="DEBUG=2".
