sizeFactors

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.
