st_is_valid operation in sf.first CRAN release
fixed lurking bug in all-POINT logic, … was passed to pslg
GEOMETRYCOLLECTION is now supported with an internal function only
GEOMETRYCOLLECTION now supported, but only as sub-geometries treated like features - a future release will triangulate a simplicial complex of the GC
introduced use of sp::over so that intersection tests are fast enough, will clean this up in future
now properly returns GEOMETRYCOLLECTION of POLYGON triangles for sfg, sfc, and sf classes. Previous versions always returned either sf or sfc, so this wasn’t consistent.
more coverage of types, will at least work for the non-exotics in an sf dataframe
first release
