MAT for multiple variables
Description
MAT for many environmental variables simultaneously. More efficient than calculating them separately 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
