mmSAR: an R-package for multimodel species-area relationship inference

The species-area relationship (SAR) is one of the most fundamental tools in ecology. After almost a century of quantitative ecology, however, the quest for a best SAR model still remains elusive, with a substantial uncertainty about the best fitting SAR model frequently being observed. Recent research has required that this uncertainty be addressed, and a multimodel SAR framework has been devised. Here we introduce the mmSAR R-package, which is a flexible and scalable implementation of the multimodel SAR framework for species-area datasets, and provide some examples of its use. This R-package provides functions for fitting SAR models, performing model selection, and the build up of multimodel SARs.
