New package: gpclib
I have just uploaded a package to CRAN called `gpclib' for clipping large
and complex polygons. This package provides an R interface to Alan
Murta's very fast General Polygon Clipper library (written in C), which
has an optimized version of the Vatti algorithm. Not all features of
Murta's library are implemented -- right now you can do intersections,
differences, and unions. There are also functions for reading/writing
from/to files and coercing between various data types.
For some more details about the package see
