### Description

Uses Fisher's exact test.

### Usage

    testSingleIndependence(ref, groups, elements, pvalueAdjust = "BH")

### Arguments

`ref` | Character: identifier of elements in reference group
`groups` | List of characters: list of groups where each element contains the identifiers of respective elements
`elements` | Character: all patient identifiers
`pvalueAdjust` | Character: method used to adjust p-values (see Details)

### Details

The following methods for p-value adjustment are supported by using the respective string in the `pvalueAdjust` argument:

- `none`: Do not adjust p-values

- `BH`: Benjamini-Hochberg's method (false discovery rate)

- `BY`: Benjamini-Yekutieli's method (false discovery rate)
