NA_z_range_

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.

Format

An object of class z_range of length 2.

Details

NA_z_range_ represents the missing value for a z_range object

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

Examples

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))
