NA_z_range_

Value

a numeric vector of length two, with zmin and zmax values; if obj is of class sf or sfc the object returned has a class z_range

Format

An object of class z_range of length 2.

Arguments

x

object of class z_range

obj

object to compute the z range from

...

ignored

crs

object of class crs, or argument to st_crs, specifying the CRS of this bounding box.

Details

NA_z_range_ represents the missing value for a z_range object

Examples

Run this code
a = st_sf(a = 1:2, geom = st_sfc(st_point(0:2), st_point(1:3)), crs = 4326)
st_z_range(a)
st_z_range(c(zmin = 16.1, zmax = 16.6), crs = st_crs(4326))
