DESeq2 (version 1.6.3)

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. See DESeq for a description of the use of size factors. If gene-specific normalization is desired for each sample, use normalizationFactors.

Usage

"sizeFactors"(object)
"sizeFactors"(object)<-value
"sizeFactors"(object)
"sizeFactors"(object) <- value

Arguments

object

a DESeqDataSet object.

value

a numeric vector, one size factor for each column in the count data.
