stamppNeisD {StAMPP}

Genetic Distance Calculation

Description

This function calculates Nei's genetic distance (Nei 1972) between populations or individuals

Usage

stamppNeisD(geno, pop = TRUE)

Arguments

geno

a data frame containing allele frequency data generated from stamppConvert, or a genlight object containing genotype data, individual IDs, population IDs and ploidy levels

pop

logical. True if genetic distance should be calculated between populations, false if it should be calculated between individual

Value

A object of class matrix which contains the genetic distance between each population or individual

Examples

# import genotype data and convert to allele frequecies
data(potato.mini, package="StAMPP")
potato.freq <- stamppConvert(potato.mini, "r")
# Calculate genetic distance between individuals
potato.D.ind <- stamppNeisD(potato.freq, FALSE)
# Calculate genetic distance between populations
potato.D.pop <- stamppNeisD(potato.freq, TRUE)
