Compute the F_ST for a sample of genes.
an object generated by the
sim.inference.model or by the
sim.coalescent command lines have been executed,
fst can be used to compute the Weir and Cockerham's (1984) estimate of F_ST for that sample. The multilocus estimator of F_ST is computed as in Genepop (Rousset 2008).

## This is to simulate a sample of genes (at a single locus), using the inference model, with ## 50 genes collected in each of 10 sampled demes. In this example, the product of ## twice the effective population size and migration rate is 2, ## and the frequency of allele A in the migrant pool is 0.5 sample <- sim.inference.model(number.of.sampled.demes = 10,sample.sizes = 50,M = 2,pi = 0.5) ## This is to compute Weir and Cockerham's (1984) estimate for that sample fst(sample)
