[GRASS-user] Using R to check points in polygons does not work

[Corrado]

Dear friends,

I attempted to solve the problem using R, as Hamish suggested.

Because there are some ring direction changes in the shape files, the 
conversion to polylist returns "NA" in some fields. When I run inout() on 
those list elements the function fails with error NA/NaN/Inf in foreign 
function call (arg 4).

Is there another method to test if a point falls in any of the polygons 
without using R? or, is there a way to solve this problem?

Best Regards
