Fstat {Geneland} | R Documentation |
Computes F statistics according to Weir and Cockerham's estimators. Missing values are allowed but as of today, the NA code is only treated as an extra allele which alters the result.
Fstat(genotypes,npop,pop.mbrship)
genotypes |
Genotypes of individuals. 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 |
A list with components
Pairwise.Fis |
A vector of estimations of within-population Fis |
Pairwise.Fst |
A matrix of estimations the pairwise population Fst. (Only the upper triangular part is returned). |
