## Exact test for Hardy-Weinberg Equilibrium for a biallelic locus

### Description

Exact test for Hardy-Weinberg Equilibrium for a biallelic locus.

### Usage

    HWE.exact(object,
              marker,
              founderOnly=TRUE)

### Arguments

`object` | a geneSet object.
`marker` | marker name for the biallelic locus.
`founderOnly` | Indicates if only founders are used to do the test.

### Value

The function `HWE` returns a list with class `htest` containing the following elements:

`statistic` | A 3-element vector records the genotype frequencies: `N11`, `N12`, `N22`.
`parameter` | A 2-element vector records the allele frequencies: `N1` and `N2`
`p.value` | p-value of the test.
`method` | Information indicates if `chisquare` method or `exact` method is used to do HWE test.
`data.name` | name of the data set
`observed` | a table lists allele levels, allele pairs, and allele codes
