NA_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.

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

Details

NA_z_range_ represents the missing value for a z_range object

Examples

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