test.between function

Tests the significance of the effect of test.lev on genetic differentiation

test.between(data, test.lev, rand.unit, nperm, ...)

Arguments

• data: a data frame containing the genotypes for the different loci
• test.lev: A vector containing the units from which to construct the contingency tables
• rand.unit: A vector containing the assignment of each observation to the units to be permutted
• nperm: The number of permutations to carry out for the test
• ...: Mainly here to allow passing diploid=FALSE if necessary

Returns

• g.star: A vector containing all the generated g-statistics, the last one beeing the observed

• p.val: The p-value associated with the test
