Hi all! How is it possible to create a qPCRset object from an expression matrix (in new veersions of HTqCR?) Thank you indeed very much.

E.g. mat <- matrix(rnorm(9*96), ncol = 6, nrow = 96, byrow = FALSE) raw <- new("qPCRset", exprs = mat, featureCategory = as.data.frame(array("OK", dim=dim(mat)))) sampleNames(raw) <- paste("S", 1:6, sep = "") featureNames(raw) <- paste("A", 1:96, sep = "") This is the simplest approach. Alternatively, if you e.g. want more information about your samples, you can add phenoData to the object either during or after creating it. See ?'qPCRset-class' for more details about the qPCRset objects.
