| copy {terra} | R Documentation |
Make a deep copy of a SpatRaster or SpatVector. This is occasionally useful when wanting to use a replacement function in a shallow copy. That is a copy that was created like this: x <- y. If you use a replacement function to change an object, its shallow copies also change.

# or make a new object like this
