object

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

value


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
<code>counts(dds, normalized=TRUE)</code>).
See <code><a rd-options="" href="/link/DESeq?package=DESeq2&version=1.12.3" data-mini-rdoc="DESeq2::DESeq">DESeq</a></code> for a description of the use of size factors. If gene-specific normalization
is desired for each sample, use <code><a rd-options="" href="/link/normalizationFactors?package=DESeq2&version=1.12.3" data-mini-rdoc="DESeq2::normalizationFactors">normalizationFactors</a></code>.


Estimate variance-mean dependence in count data from
high-throughput sequencing assays and test for differential
expression based on a model using the negative binomial
distribution.

sizeFactors function

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
