bes_g_cushman: Configurational entropy for surfaces

Description

Calculates Cushman's configurational entropy for surfaces (2021)

Usage

bes_g_cushman(x, nr_of_permutations = 1000, independent = FALSE)

Value

A tibble

Arguments

x

SpatRaster, stars, RasterLayer, RasterStack, RasterBrick, matrix, or array containing one or more continuous rasters

nr_of_permutations

Number of permutations performed on each input raster to calculate possible distribution of "slope" values

independent

Should an independent set of permutations be performed for each input raster? TRUE/FALSE. Use FALSE (default) when each of your input rasters has the same configuration.
