biomod2 (version 3.1-25)

BIOMOD_LoadModels: Load models built within BIOMOD_Modeling function

Description

This function was implemented to help biomod2 users to load individual models built during the BIOMOD_Modeling step.

Usage

BIOMOD_LoadModels(bm.out, ... )

Arguments

bm.out

a "BIOMOD.models.out" returned by BIOMOD_Modeling

...

additional arguments (see details)

Value

• A character vector filled with the loaded models names.

itemize

• models:

sQuote

• GLM
• GAM
• RF
• RUN1
• Full
• PA1
• PA2

item

• run.eval:
• data.set:
• path:

Details

This function is particulary useful when you plane to make some response plot analyses. It will induce models, built at BIOMOD_Modeling step, loading in your working space. If you run this function referencing only bm.out argument, all models built will be loaded. However, you can make a models subselection using the additional arguments (see below).
