[R-sig-Geo] select polygons in polygons

[Murray Richardson]

Thanks Friderike.  I assumed this was the answer, but it doesn't appear 
to work with two SPDF objects.  i.e.:

 > overlay(polysA,polysB)
Error in function (classes, fdef, mtable)  :
  unable to find an inherited method for function "overlay", for 
signature "SpatialPolygonsDataFrame", "SpatialPolygonsDataFrame"
