Gst_Hedrick {mmod}

Calculate Nei's Gst using estimators for Hs and Ht

Description

This function calculates Hedrick's G'st from a genind object

Usage

Gst_Hedrick(x)

Arguments

x

genind object (from package adegenet)

Details

Takes a genind object with population information and calculates Hedrick's G”st.

Because estimators of Hs and Ht are used, it's possible to have negative estimates of G”st. You should treat such results as zeros (or an attempt to estimate a very low number with some error which might push it below zero)

Value

per.locus values for each G”st for each locus in the dataset

global estimtes for G”st based on overall heterozygosity
