Dear all,
I apologize if this is too simple a question as it does appear to be a basic
GIS operation but I have not found the appropriate function that performs a
clipping of polygons into boundaries given by a (larger "outer") polygon. I
tried overlay() from package sp and clipPolys from package PBSmapping but
none converted the "inner" polygons into new ones laying inside the
boundaries given by the outer polygon.

Any help would be greatly appreciated,
Thanks,

Markus
