Description

Constructor function for stageRClass. A stageR class is a class used for stage-wise analysis in high throughput settings. In its most basic form, it consists of a vector of p-values for the screening hypothesis and a matrix of p-values for the confirmation hypotheses.

Usage

1
stageR(pScreen, pConfirmation, pScreenAdjusted = FALSE)

Arguments

pScreen

A vector of screening hypothesis p-values.

pConfirmation

A matrix of confirmation hypothesis p-values. When constructing a stageRClass object, the number of rows should be equal to the length of pScreen. For a stageRTxClass object, the dimensions can be different.

pScreenAdjusted

logical, indicating whether the supplied p-values for the screening hypothesis have already been adjusted for multiplicity according to the FDR.

...

Additional arguments.

Value

An instance of an object of the stageRClass
