ddCt Expression

Description

This class is a subclass of ExpressionSet and represents objects which are produced by the ddCt algorithm in the ddCtExpression method

Extends

Class ExpressionSet, directly. Class eSet, by class "ExpressionSet", distance 2. Class VersionedBiobase, by class "ExpressionSet", distance 3. Class Versioned, by class "ExpressionSet", distance 4.

Methods

dCt

signature(object = "ddCtExpression"): returns the dCt value of this ddCtExpressionobject

dCtErr

signature(object = "ddCtExpression"): returns the error number of the dCt value of this ddCtExpressionobject

ddCt

## read a SDM file
sampdat <- SDMFrame(system.file("extdata", "Experiment1.txt",
                                package="ddCt"))

## call ddCtExpression method to get a ddCt calculated expression
result <- ddCtExpression(sampdat,
                         calibrationSample="Sample1",
                         housekeepingGenes=c("Gene1","Gene2"))

## use getter methods
ddCt(result)
ddCtErr(result)
