Basically the same way as before ;)
There's an example is the vignette, but in the (admittedly not very
informative titled) "Additional devices" section. E.g.
mat <- matrix(rnorm(9*96), ncol = 6, nrow = 96, byrow = FALSE)
raw <- new("qPCRset", exprs = mat, featureCategory =
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.
