ecospat (version 3.3)

ecospat.climan: A climate analogy setection tool for the modeling of species distributions

Description

Assess climate analogy between a projection extent (p) and a reference extent (ref, used in general as the background to calibrate SDMs)

Usage

ecospat.climan (ref, p)

Value

Returns a vector. Values below 0 are novel conditions at the univariate level (similar to the MESS), values between 0 and 1 are analog and values above 1 are novel covariate condtions. For more information see Mesgeran et al. (2014)

Arguments

ref

A dataframe with the value of the variables (i.e columns) for each point of the reference exent.

p

A dataframe with the value of the variables (i.e columns) for each point of the projection exent.
