Purpose

The R package 'MaxentVariableSelection' helps selecting the most important set of uncorrelated environmental variables along with the optimal regularization multiplier for Maxent Niche Modeling. This allows constrain model complexity, and thus, to increase model peformance and transferability of habitat suitability to novel environmental conditions (e.g. future climate scenarios).

Installation

To install and load the package from CRAN, type:

install.packages("MaxentVariableSelection")
library(MaxentVariableSelection)

To install and load the package from github, type:

install.packages("devtools") 
devtools::install_github("alj1983/MaxentVariableSelection")
library(MaxentVariableSelection)

Documentation

The folder 'vignettes' contains documentation files that show how to use the package. The main function of the package (VariableSelection) and the example datasets in 'inst/extdata' are described in the 'MaxentVariableSelection-manual.pdf'.
