Perhaps have a look at the sp package and especially the over function.

Emne: [R] index polygons
Hello,
I need to compare a polygon with a set of other polygons.
I'd like to index polygons with a grid in order not to compare definitely
distant ones.
How can I do this?
I need
1. Transform polygons to cells
2. Find cell neighbors (defined cell distance) for a polygon
Thanks
Leonid
