DJ {FinePop}

Jost's D

Description

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

Usage

DJ(popdata)

Arguments

popdata

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

Value

Matrix of estimated pairwise Jost's D.

Examples

# Example of GENEPOP file
data(jsmackerel)
jsm.ms.genepop.file <- tempfile()
jsm.popname.file <- tempfile()
cat(jsmackerel$MS.genepop, file=jsm.ms.genepop.file, sep="\n")
cat(jsmackerel$popname, file=jsm.popname.file, sep=" ")

# Data load
# Prepare your GENEPOP file and population name file in the working directory
# Replace "jsm.ms.genepop.file" and "jsm.popname.file" by your file names.
popdata <- read.genepop(genepop=jsm.ms.genepop.file, popname=jsm.popname.file)
