raster.overlap: raster.overlap, measures overlap between two ENMs

In ENMTools: Analysis of Niche Evolution using Niche and Distribution Models

raster.overlap, measures overlap between two ENMs

Description

This function measures similarity in the geographic distribution of suitability scores from two ENMs. It returns two metrics, I and D. These metrics are described in Warren et al. 2008.

Usage

raster.overlap(x, y, verbose = FALSE)

Arguments

x	A raster or RasterLayer object, or ENMTools model object containing a suitability raster.
y	Another raster or RasterLayer object, or ENMTools model object containing a suitability raster.
verbose	Controls printing of diagnostic messages

Value

results A vector containing the three metrics (I, D, and Spearman rank correlation)

Examples

aurelioi.glm <- enmtools.glm(iberolacerta.clade$species$aurelioi,
euro.worldclim, f = pres ~ bio1 + bio12)
aranica.glm <- enmtools.glm(iberolacerta.clade$species$aranica,
euro.worldclim, f = pres ~ bio1 + bio12)
raster.overlap(aurelioi.glm, aranica.glm)
