R package diveRsity. Allows the calculation of both genetic diversity partition statistics, genetic differentiation statistics, and locus informativeness for ancestry assignment. It also provides users with various option to calculate bootstrapped 95% confidence intervals both across loci, for pairwise population comparisons, and to plot these results interactively. Parallel computing capabilities and pairwise results without bootstrapping are provided. Weir and Cockerham’s 1984 F-statistics are also calculated. Various plotting features are also provided, as well as Chi-square tests of genetic heterogeneity are also provided. Functionality for the calculation of various diversity parameters is possible for RAD-seq derived SNP data sets containing thousands of marker loci. A shiny application for the development of microsatellite multiplexes is also available.
