mat_pw_fst {graph4lg}R Documentation

Compute a pairwise FST matrix between populations

Description

The function computes the pairwise FST matrix between populations from an object of class genind

Usage

mat_pw_fst(x)

Arguments

x

An object of class genind

Details

The formula used is that of Weir et Cockerham (1984). This functions uses directly the function pairwise.WCfst from hierfstat.

Value

A pairwise matrix of FST with as many rows and columns as there are populations in the input data.

Warnings

Negative values are converted into 0
