The betadiv package is licensed under the GNU Lesser General Public License v3.0 (LGPL-3).
The betadiv package implements the multiple-site dissimilarity indices of Simpson, Sorensen and nestedness, which can be used to assess the beta diversity of a population. These indices were adapted from those developed by Baselga (2010, Global Ecology and Biogeography 19:134--143) in order to make them population size-independent. All the details behind the calculation and estimation of these adapted indices can be found in Fortin et al. (2020, Global Ecology and Biogeography 29: 1073-1084).
The betadiv package depends on the J4R package. The dissimilarity indices are estimated using three Java libraries: betadivcalc, repicea, and repicea-mathstats. All are licensed under the Lesser GNU General Public License v3.0 (LGPL-3). This package and the associated Java libraries come with absolutely NO WARRANTY.
