Examples

library(faahKO)
xset <- group(faahko)
xset <- retcor(xset)
xset <- group(xset)
xset <- fillPeaks(xset)
peaksData <- as.data.frame(groupval(xset,"medret",value="into"))
peaksData$name <- row.names(peaksData)
para <- new("metaXpara")
rawPeaks(para) <- peaksData
sampleListFile(para) <- system.file("extdata/faahKO_sampleList.txt", 
    package = "metaX")
para <- reSetPeaksData(para)
plotIntDistr(para)
## after normalization
para <- metaX::normalize(para)
plotIntDistr(para)
