dispersionFunction(object, ...)
dispersionFunction(object, ...) <- value
"dispersionFunction"(object)
"dispersionFunction"(object,estimateVar)<-value
"dispersionFunction"(object)

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.
