Randomization of presence/absence species distribution raster data for calculating standardized effect sizes and testing null hypothesis. The randomization algorithms are based on classical algorithms for matrices (Gotelli 2000, doi:10.2307/177478) implemented for raster data.
To install the package, run:
install.packages("SESraster")
The development version can be installed from the Github repository:
require(devtools)
install_github("HemingNM/SESraster", build_vignettes = TRUE)
Basic information about the package can be found below, at the package's webpage, or in the vignettes browseVignettes("SESraster")
vignette("null-models"): For an overview of the null model algorithms for species co-occurrence analysis summarized in (Gotelli 2000, doi:10.2307/177478).
vignette("spatial-null-models"): Get started with SESraster. See installation instructions and how the implemented null model algorithms work with spatial data.
vignette("SES"): For computing standardized effect sizes (SES) using the implemented null model algorithms.
