### Description

This is an internal function run within RR framework. It performs Reference Ranges Plus test and after that Fisher Exact test on calculated count matrices. As an internal function, it doesn't include extensive error testing of inputs. Please use cautiously if calling directly.

Works with `PhenList` object created by `PhenList` function.

### Usage

        RRTest(
    		  phenList,
    		  depVariable,
    		  outputMessages = TRUE,
    		  naturalVariation = 95,
    		  controlPointsThreshold = 60
    )

### Arguments

`phenList` | instance of the `PhenList` class; mandatory argument
`depVariable` | a character string defining the dependent variable of interest; mandatory argument
`outputMessages` | flag: "FALSE" value to suppress output messages; "TRUE" value to show output messages; default value TRUE
`naturalVariation` | number defining the natural variation range in percents for normal values; default value 95
`controlPointsThreshold` | number defining how many control points is needed to perform RR plus method; default value 60
