This repository contains data and scripts used to perform the analyses presented in "Visualizing Species Richness and Site Similarity from Presence-absence Matrices."
All analyses and plots can be reproduced using the script "Visualizing_PAMs.R". Executing the code in this script will bring the data and an extra function to the R environment.
Data:
A presence-absence matrix (PAM) composed of 1595 species of terrestrial vertebrates, on a grid of 711 cells (resolution of 0.5°). This PAM derived from IUCN data and was created by Raul Sierra from CONABIO, Mexico. The original data used were IUCN shapefiles of the terrestrial world vertebrates, and then "clipped" to Mexico.
The data is in two formats: 1) cvs table, and 2) .RData format
