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"

Subject: [R-sig-Geo] select polygons in polygons
Hello users,
There is probably a very simple solution to this that I am missing: is
there a way to select polygons in one SPDF that fall within the polygons
of another SPDF?
This would save me a lot of processing time as I am having to take a
very circuitous route to achieve the same outcome.
Thanks!
Murray
