⚠️There's a newer version (1.7-7-1) of this package.Take me there.

untb (version 1.7-2)

ecological drift under the UNTB

Description

A collection of utilities for biodiversity data. Includes the simulation of ecological drift under Hubbell's Unified Neutral Theory of Biodiversity, and the calculation of various diagnostics such as Preston curves. Now includes functionality provided by Francois Munoz and Andrea Manica.
