Scripts for creating maps and performing niche modeling using R.
The general workflow is as follows:
mapping.R: importing taxon occurrence data into R, creating maps, creating custom shapefileslayerPrep.R: masking/clipping BioClim layers, looking for correlations between layersmaxent.R: creating niche models using occurrence data and climate layersnicheOverlap.R: assessing whether niche models for different taxa are distinct from each other
There are a number of files and directories that are downloaded or created during this analysis. To perform all commands in layerPrep.R, you should download the BioClim layers and store them in a convenient place (note the paths for using these layers may need to be changed). Clipped layers are included in layers/ for your convenience.
