Fst {pegas} | R Documentation |
This function computes the Fit, Fst and Fis for each locus in the data.
Fst(x, pop = NULL)
x |
an object of class "loci" . |
pop |
a vector or factor giving the population assignment of each
row of x , or a single numeric value specifying which column
of x to use as population indicator. By default, the column
labelled "population" is used. |
The formulae in Weir and Cockerham (1984) are used for each allele, and then averaged within each locus over the different alleles as suggested by these authors.
A matrix with genes (loci) as rows and the three F-statistics as columns.
This function has not been tested thoroughly, so the results need to be taken with some caution.
