+This repository contains the code and data used to generate the final ensemble species distribution model (SDM). 
 
 The code was developed in R Studio, under R version 4.0.3. The R code file is "EnsembleSDMCode4_12.R" in this repository. 
 
+## Data
 The "Data" folder contains the archaeological sites used as presence points for the ensemble SDM. 
 The "Data" folder also contains the enviornmental variables used to generage the ensemble SDM. Environmental variables are in .tif format. See "Potential distributions of pre-Columbian people in Tropical Andean landscapes" for more details.
