simba-package: Calculate similarity measures for binary data

In simba: A Collection of functions for similarity analysis of vegetation 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.

Details

Package:	simba
Type:	Package
Version:	0.3-5
Date:	2012-12-06
License:	GPL version 2

The functions in this package can be used to calculate similarities between species records (in binary format). Functions related to the correlation of similarity matrices and some other useful functions for the analysis of spatial patterns and their change in time are included as well.
