## read a SDM file 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 ## sampdat <- readSDM(system.file("extdata", "Experiment1.txt", ## 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 uniqueDetectorNames(sampdat) <- c(Gene1="NewGene1", Gene2="NewGene2") uniqueDetectorNames(sampdat)
