Get the bounding box from the x object

If the x does not have a CRS, WGS84 is assumed.

Usage

as_bbox(x)

Arguments

x

Simple feature object (or compatible) or a bounding box, provided either as a matrix (with x, y as rows and min, max as columns) or as a vector (xmin, ymin, xmax, ymax)

Value

A bounding box as returned by sf::st_bbox()
