NA_m_range_

Value

a numeric vector of length two, with mmin and mmax values; if obj is of class sf or sfc the object if obj is of class sf or sfc the object returned has a class m_range

Format

An object of class m_range of length 2.

Arguments

x

object of class m_range

obj

object to compute the m range from

...

ignored

crs

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

Details

NA_m_range_ represents the missing value for a m_range object

Examples

Run this code
a = st_sf(a = 1:2, geom = st_sfc(st_point(0:3), st_point(1:4)), crs = 4326)
st_m_range(a)
st_m_range(c(mmin = 16.1, mmax = 16.6), crs = st_crs(4326))
