hw.test {pegas} | R Documentation |
This function tests, for a series of loci, the hypothesis that genotype frequencies follow the Hardy–Weinberg equilibrium.
hw.test(x, B = 1000)
x |
an object of class "loci" . |
B |
the number of replicates for the Monte Carlo procedure. |
This test can be performed with any level of ploidy. Two versions
of the test are available: the classical chi^2-test based
on the expected genotype frequencies calculated from the allelic
frequencies, and an exact test based on Monte Carlo permutations of
alleles. The latter version is available only for diploids. Set
B = 0
if you want to skip the latter test.
a matrix with three or four columns with the chi^2-value,
the number of degrees of freedom, associated P-value, and
possibly the P-value from the Monte Carlo test. The rows of
this matrix are the different loci in x
