g.stats: Calculates likelihood-ratio G-statistic on contingency table
Description
Calculates the likelihood ratio G-statistic on a contingency table of alleles at one locus X sampling unit. The sampling unit could be any hierarchical level
Usage
g.stats(data,diploid=TRUE)
Arguments
data
a two-column data frame. The first column contains the sampling unit, the second the genotypes
diploid
Whether the data are from diploid (default) organisms
g.statsThe likelihood ratio statistics, $2 \sum(O \log(\frac{O}{E}))$
