## 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

Ct

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

CtErr

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

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

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

ddCtErr

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

level

  `signature(object = "ddCtExpression")`: returns the levels in this ddCtExpressionobject

levelErr

elist

  `signature(object = "ddCtExpression")`: returns a data frame which represents this expression object

### Examples

    ## 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)
