dispersionFunction(object, ...)

dispersionFunction(object, ...) <- value

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

## S4 replacement method for signature 'DESeqDataSet,'function''
dispersionFunction(object,
  estimateVar = TRUE) <- value

Arguments

object

a DESeqDataSet object.

...

additional arguments

value

a function

estimateVar

whether to estimate the variance of dispersion residuals. setting to FALSE is needed, e.g. within estimateDispersionsMAP when called on a subset of the full dataset in parallel execution.

Details

Setting this will also overwrite mcols(object)$dispFit and the estimate the variance of dispersion residuals, see estimateVar below.
