exoCount {ChIPSeqSpike} | R Documentation

## Set the number of reads associated to an experiment

### Description

Set the number of exogenous reads associated to an experiment. This is used to compute scaling factors.

### Usage

    exoCount(theObject) <- value

    ## S4 replacement method for signature 'Experiment'
    exoCount(theObject) <- value

    ## S4 replacement method for signature 'ExperimentLoaded'
    exoCount(theObject) <- value

### Arguments

`theObject` | An Experiment or ExperimentLoaded object
`value` | A numeric representing the number of mapped reads to the exogenous reference genome

### Value

The modified object is returned
