Internal function to prepare allele and genotype frequencies for F statistics. Rows with NA
values are removed from the calculation.
1  Fis(tab.pop, allele.column)

tab.pop 
Object with information for one or several populations and loci. Format needs to be in accordance with inputformat. 
allele.column 
Loci information from column 
Be sure to remove all missing data in your data file. Prior to calculation of F_{is} values. Every sample containing NA
values in any column will be removed. It may be better to remove complete loci columns to get good results. In any case you should check this.
tab.freq 
Table of allele frequencies 
tab.freq.gen 
Table of genotype frequencies 
Homo 
Sum of homozygotes 
pop.size 
Population size 
Fis 
F_{is} values calculated according to Nei 1983 
Fis.weir 
F_{is} values calculated according to Weir and Cockerham 1984
