Spatial* objectsMethods to coerce simple feature objects to Spatial* objects
as_Spatial(from, cast = TRUE, IDs = paste0("ID", 1:length(from)))object of class sfc_POINT, sfc_MULTIPOINT, sfc_LINESTRING, sfc_MULTILINESTRING, sfc_POLYGON, or sfc_MULTIPOLYGON.
logical; if TRUE, st_cast from before converting, so that e.g. GEOMETRY objects with a mix of POLYGON and MULTIPOLYGON are cast to MULTIPOLYGON.
character vector with IDs for the Spatial* geometries
geometry-only object deriving from Spatial, of the appropriate class
