bes_m_cushman {bespatial}

Configurational entropy for landscape mosaics

Description

Calculates Cushman's configurational entropy for landscape mosaics (2015)

Usage

bes_m_cushman(x, nr_of_permutations, independent = FALSE)

Arguments

x

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

nr_of_permutations

Number of permutations performed on each input raster to calculate possible distribution of total edge 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 (proportion of categories).

Value

A tibble
