wk_crs_inherit: Special CRS values

Description Usage Arguments Examples

View source: R/wk-crs.R

Description

The CRS handling in the wk package requires two sentinel CRS values. The first, wk_crs_inherit(), signals that the vector should inherit a CRS of another vector if combined. This is useful for empty, NULL, and/or zero-length geometries. The second, wk_crs_auto(), is used as the default argument of crs for constructors so that zero-length geometries are assigned a CRS of wk_crs_inherit() by default.
