sizeFactors {DESeq2} | R Documentation

## Accessor functions for the 'sizeFactors' information in a DESeqDataSet object.

### Description

The sizeFactors vector assigns to each column of the count matrix a value, the size factor, such that count values in the columns can be brought to a common scale by dividing by the corresponding size factor (as performed by `counts(dds, normalized=TRUE)`). See `DESeq` for a description of the use of size factors. If gene-specific normalization is desired for each sample, use `normalizationFactors`.

### Usage

    ## S4 method for signature 'DESeqDataSet'
    sizeFactors(object)

    ## S4 replacement method for signature 'DESeqDataSet,numeric'
    sizeFactors(object) <- value

### Arguments

`object` | a `DESeqDataSet` object.
`value` | a numeric vector, one size factor for each column in the count data.
