Provides functions for uniform sampling of the environmental space, designed to assist species distribution modellers in gathering ecologically relevant pseudo-absence data. The method ensures balanced representation of environmental conditions and helps reduce sampling bias in model calibration. Based on the framework described by Da Re et al. (2023)
The USE R package offers a collection of functions that enable the uniform sampling of the environmental space. It was specifically developed to assist species distribution modellers in gathering ecologically relevant pseudo-absences by uniformly sampling the environmental space.
The development version of USE can be installed running the code below:
# Install the released version from CRAN
# install.packages("USE") #not available yet
# Or the development version from GitHub:
# install.packages("devtools")
devtools::install_github("danddr/USE")

Examples showing how to implement USE for species distribution modelling are provided in the dedicated vignette, and can also be found at https://github.com/danddr/USE_paper/tree/main/Example.
