Description Usage Arguments Value Examples
This calculates Fst. The caluclation is done as (Ht-Hs)/Ht, where Ht is the expected heterozygosity for all populations and Hs is the expected heterozygosity for each population. This calculation is used in bootstrapping functions.

df |
A dataframe containing the genepop information, where the first column is the population ID. |
i |
Column number containing genotype information. |
ht |
The expected heterozygosity under Hardy-Weinberg expectations. This is a single numerical value. |
fst |
The calculated Fst value for this locus. |
