This document describes the phyloregion package for the R software. phyloregion is a computational infrastructure for biogeographic regionalization (the classification of geographical areas in terms of their biotas) and spatial conservation in the R scientific computing environment. Previous analyses of biogeographical regionalization were either focused on smaller datasets or slower particularly when the number of species or geographic scale is very large. With macroecological datasets of ever increasing size and complexity, phyloregion offers the possibility of handling and executing large scale biogeographic regionalization efficiently and with extreme speed. It also allows fast and efficient for analysis of more standard conservation measures such as phylogenetic diversity, phylogenetic endemism, evolutionary distinctiveness and global endangerment. phyloregion can run on any operating system (Mac, Linux, Windows or even high performance computing cluster) with R 3.6.0 (or higher) installed.

## Installation

phyloregion is an open-source and free package hosted on GitHub. You will need to install the devtools package. In R, type:

if (!requireNamespace("devtools", quietly = TRUE)) install.packages("devtools")

Then:
