diff_stats: Calculate differentiation statistics for a genind object

In dwinter/mmod: Modern Measures of Population Differentiation

Description

By default this function calculates three different statistics of differentiation for a genetic dataset. Nei's Gst, Hedrick's G”st and Jost's D. Optionally, it can also calculate Phi'st, which is not calculated by default as it can take somewhat more time to run.

Usage

diff_stats(x, phi_st = FALSE)

Arguments

x	genind object (from package adegenet)
phi_st	Boolean Calculate Phi_st (default is FALSE)

Details

See individual functions (listed below) for more details.

Value

per.locus values for each statistic for each locus in the dataset

global estimtes for these statistics across all loci in the dataset
