Species suitability change between climate scenarios

Usage

suit.change(r1, r2, filename = "")

Arguments

r1: A SpatRaster with presence-absence data (0 or 1) for a set of species.
r2: A SpatRaster with presence-absence data (0 or 1) for a set of species.
filename: Character. Save results if a name is provided.

Value

A SpatRaster with suitability change (gain, loss, unchanged, and unsuitable).

r1 <- terra::rast(system.file("extdata", "ref.tif",
package = "divraster"))
r2 <- terra::rast(system.file("extdata", "fut.tif",
