Fstat: Computes F statistics on a population genetics dataset given as R
object
Description
Computes F statistics according to Weir and Cockerham's
estimators.
Missing values are allowed and accounting for in the computation of
Fst.
The presence of missing values involves a downward bias in the
computation of Fis.
This function should not be used on haploid data.
Usage
Fstat(genotypes,npop,pop.mbrship,ploidy)
Arguments
genotypes
Diploid codominant genotype data. A matrix with one line per
individual and 2 columns per locus
npop
total number of popluation present in the dataset
pop.mbrship
Vector of integers giving the population membership
for each individual
ploidy
Integer: 1 or 2 (default is 2) under development. Do
not use for haploid data.
