Niche equivalency
Description
Compute niche equivalency for two species following Warren et al. (2009). The statistic ranges from 0 to 1.
Usage
nicheEquivalency(sp1, sp2, predictors, n=99, model=maxent, verbose=TRUE, ...)
Arguments
sp1
coordinates for species 1 (matrix with (x, y) or (lon, lat), or SpatialPoints)
sp2
coordinates for species 2 (matrix with (x, y) or (lon, lat), or SpatialPoints)
predictors
Raster object with environmental variables
n
integer. Number of randomizations
model
function. modeling algorithm to me used
verbose
logical. If TRUE some progress indicators are printed
...
additional arguments (none)
Value
numeric
Author(s)
Brian Anacker. Based on a similar function in by Christoph Heibl in the phyloclim package
