⚠️There's a newer version (0.3-5) of this package.Take me there.

simba (version 0.2-5)

A Collection of functions for similarity calculation of binary data

Description

Besides a function for the calculation of similarity measures with binary data (for instance presence/absence species data) the package contains some simple wrapper functions for reshaping species lists into matrices and vice versa and some other functions for further processing of similarity data (Mantel-like permutation procedures) as well as some other useful stuff.
