Hello. Currently GEOS C API interface has been already available. And RCppTemplate package is also available.
I think GEOS's functions are far better than gpclib's. It can manipulate points, linestrings, polygons and multi-geometries and it has lots of functions(ca. buffer, union, overlay query/analysis) If R interface to GEOS, one of core functions of creating spatial weight matrices will be easy, faster and correct since current spdep took time to build them. Does any one have plan to build R interface using above packages?
