This repo contains R source code used to carry out the majority of the analysis for the upcoming paper Mapping the zoonotic niche of Marburg virus disease in Africa Note that this repo is intended to allow readers to scrutinise the methodological approaches used, but not to fully reproduce the analysis, since the analysis relies on a number of very large data files (raster imagery, occurrence data etc.) The code is also designed to run on a 64-core machine so the model fitting would likely be very slow on most machines.
