Arguments

x

object of class sf, sfc or sfg

...

ignored

Value

matrix with coordinates (X, Y, possibly Z and/or M) in rows, possibly followed by integer indicators L1,...,L3 that point out to which structure the coordinate belongs; for POINT this is absent (each coordinate is a feature), for LINESTRING

L1 refers to the feature, for MULTILINESTRING

L1 refers to the part and L2 to the simple feature, for POLYGON

L1 refers to the main ring or holes and L2 to the simple feature, for MULTIPOLYGON

L1 refers to the main ring or holes, L2 to the ring id in the MULTIPOLYGON, and L3 to the simple feature.
