Description Usage Arguments Value Author(s) References See Also Examples

View source: R/GstN.R

Description

This function estimates pairwise Gst among subpopulations (Nei 1973) from a GENEPOP data object (Rousset 2008). Missing genotype values in the GENEPOP file ("0000" or "000000") are simply ignored.

Usage

1
GstN(popdata)

Arguments

popdata

Population data object created by read.genepop function from a GENEPOP file.

Value

Matrix of estimated pairwise Gst.
