biomod2 (version 3.5.1)

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, ... )

Value

A character vector filled with the loaded models names.

Arguments

bm.out

a "BIOMOD.models.out" returned by BIOMOD_Modeling

...

additional arguments (see details)

Author

Damien Georges

Details

This function is particularly 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).

Additional arguments (...) : All the following arguments are optional.

• models: a character vector defining the names of models (e.g c(‘GLM’, ‘GAM’, ‘RF’) ) you want to load (models subselection)

• run.eval: a character vector defining the names of evaluation run (e.g c(‘RUN1’, ‘Full’) ) you want to load (repetition subselection)

• data.set: a character vector defining the names of data.set (e.g c(‘PA1’, ‘PA2’)) you want to load (pseudo absences subselection)

• path: the path to file where the species folder is. To be filled if species folder is different from your working directory)
