Niche equivalency

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
