bes_p_cushman {bespatial}

Configurational entropy for point patterns

Description

Calculates Cushman's configurational entropy for point patterns (2021)

Usage

bes_p_cushman(x, nr_of_permutations, independent = FALSE)

Arguments

x

SpatRaster, stars, RasterLayer, RasterStack, RasterBrick, matrix, or array containing one or more rasters with one value and NAs

nr_of_permutations

Number of permutations performed on each input raster to calculate possible distribution of the number of nearest neighbors

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.

Value

A tibble

Examples

  library(terra)
  library(bespatial)
  point_pattern = rast(system.file("raster/point_pattern.tif", package = "bespatial"))
  ce3 = bes_p_cushman(point_pattern, 100)
  plot(point_pattern, main = round(ce3$value, 2))
  ce3b = bes_p_cushman(point_pattern, 100, independent = TRUE)
  plot(point_pattern, main = round(ce3b$value, 2))
