multi.mat: MAT for multiple variables

Description

MAT for many environmental variables simultaneously. More efficient than calculating them seperately for each variable.

Usage

multi.mat(training.spp, envs, core.spp, noanalogues = 10, method = "sq-chord",
    run = "both")

Arguments

training.spp

Community data

envs

Environmental variables - or simulations

core.spp

Optional fossil data to make predictions for

noanalogues

Number of analogues to use

method

distance metric to use

run

Return LOO predictions or predictions for fossil data

Value

Matrix of predictions

Examples

# NOT RUN {

data(arctic.pollen)
