countMatrix {srnadiff} | R Documentation

## Accessors for the 'countMatrix' slot of an srnadiffExp object

### Description

The `countMatrix` slot holds the count matrix from the DERs found.

### Usage

    ## S4 method for signature 'srnadiffExp'
    countMatrix(object)

### Arguments

`object` | An `srnadiffExp` object.

### Details

In the last step of an sRNA-diff approach, the potential DERs is assessed. Reads (including fractions of reads) that overlap each expressed region are counted to arrive at a count matrix with one row per region and one column per sample. This matrix to been used for quantify the statistic signification of the finded regions.

### Value

A matrix with the number of reads for each regions, and each sample.

### Examples

    srnaExp <- srnadiffExample()
    srnaExp <- srnadiff(srnaExp)
    countMatrix(srnaExp)
