snphwe: Exact test of Hardy--Weinberg.

Description

Computes a p-value for the exact test of Hardy--Weinberg proportions, for genotype counts for a biallelic locus, as described by Wiggington et al. (2005)

Usage

snphwe(g)

Arguments

g
Vector of genotypes.

Value

The p-value.

Details

This function is a wrapper for snphweCounts, which uses code by Wiggington et al. to compute a P-value for an exact test of Hardy--Weinberg proportions. This function requires that when g is sorted, the order is hom/het/hom. For example g can be additively coded genotypes (0, 1, 2), or text coded genotypes like AA, AC, CC. For text coded genotypes the heterozygote MUST ALWAYS be coded the same way, e.g. a mixture of AC and CA are not allowed.

Examples

Run this code
snphwe(rbinom(100, 2, 0.2))
