Arguments

obj

object to compute the bounding box from

Value

a numeric vector of length four, with xmin, ymin, xmax and ymax values; if obj is of class sf or sfc, the object returned has a class bbox, an attribute crs and a method to print the bbox and an st_crs method to retrieve the coordinate reference system corresponding to obj (and hence the bounding box).

Format

An object of class bbox of length 4.

Details

NA_bbox_ is the bbox object with a missing value.
