In one of the example in SLqPCRdata package stated below, I am unsure
in the last line i.e. exprData <- normPCR(SLqPCRdata, c(3,4)), whether
SLqPCRdata should have been relData ? According to the help page of
normPCR, it requires a data.frame containing relative quantities.
SLqPCRdata contains the average take-off values, but relData contains
relative expression values for realtime quantitative RT-PCR data based
on take-off values.

relData <- apply(SLqPCRdata, 2, relQuantPCR)
exprData <- normPCR(SLqPCRdata, c(3,4))
