    sampdat <- SDMFrame(system.file("extdata", "Experiment1.txt",
                                    package="ddCt"))
    ## you can also write
    ## sampdat <- new("SDMFrame",system.file("extdata", "Experiment1.txt",
    ##                                       package="ddCt"))

    ## or with

    ##                                package="ddCt"))

    ## use the getter methods
    sampleNames(sampdat)

    ## or the overloaded primitive accessors
    sampdat[1:3,"Sample"]

    ## see all unique samples
    uniqueSampleNames(sampdat)

    ## replace all sample names 'Sample1' and 'Sample2' in sampdat
    ## with 'NewSample1' and 'NewSample2'
    uniqueSampleNames(sampdat,c("Sample1","Sample2")) <- c("NewSample1","NewSample2")
    uniqueSampleNames(sampdat)

    ## or use this syntax to replace the gene names
