Description: Tools for constructing niche models and analyzing patterns of niche evolution. Acts as an interface for many popular modeling algorithms, and allows users to conduct Monte Carlo tests to address basic questions in evolutionary ecology and biogeography. Warren, D.L., R.E.

background.points.buffer function

Takes a set of points, a buffer radius, a sample size, and a mask and returns
randomly sampled points from within that buffer radius.
