Gst_Hedrick: 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)
Value
per.locus values for each G''st for each locus in the datasetglobal estimtes for G''st based on overall heterozygosity
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)
