trimdupes.by.raster

Takes a set of points and a raster mask and returns a data frame trimmed so that only one point is returned per grid cell in the mask raster.

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.
