[R-sig-Geo] Checking whether SpatialPolygons includes SpatialLines

[Satoshi KOIDE]

Hi All,

I need a function which checks whether SpatialPolygons object includes
SpatialLines object.
If the polygon is convex, it is possible to use point.in.polygon(),
however, in non-convex case, it is not sufficient.
Does anyone have a good idea?

thanks,

Satoshi Koide
