## Obtain Venn Counts for Venn Diagram, internal function for makeVennDigram

### Description

Obtain Venn Counts for two peak ranges using chromosome ranges or feature field, internal function for makeVennDigram

### Usage

    findVennCounts(Peaks, NameOfPeaks, maxgap = -1L, minoverlap = 0L,
                   totalTest, useFeature=FALSE)

### Arguments

`Peaks` | RangedDataList: See example below.
`NameOfPeaks` | Character vector to specify the name of Peaks, e.g., c("TF1", "TF2"), this will be used as label in the Venn Diagram.
`maxgap,minoverlap` | Used in the internal call to `findOverlaps()` to detect overlaps. See `?findOverlaps` in the IRanges package for a description of these arguments.
`totalTest` | Numeric value to specify the total number of tests performed to obtain the list of peaks.
`useFeature` | TRUE or FALSE, default FALSE, true means using feature field in the RangedData for calculating overlap, false means using chromosome range for calculating overlap.

### Value

`p.value` | hypergeometric testing result
`vennCounts` | vennCounts objects containing counts for Venn Diagram generation, see details in limma package vennCounts
