Get a SpatExtent of a SpatRaster, SpatVector, or other spatial objects. Or create a SpatExtent from a vector (length=4; order=xmin, xmax, ymin, ymax)
You can set the extent of a SpatRaster, but you cannot set the extent of a SpatVector (see rescale
for that). See set.ext
to set the extent in place.
