This class inherits directly from class list, so DGEList objects can be manipulated as if they were ordinary lists. However they can also be treated as if they were matrices for the purposes of subsetting. The dimensions, row names and column names of a DGEList object are defined by those of counts, see dim.DGEList or dimnames.DGEList. dairy cow vs meat cowdairy cream butter gramsWebIn the limma-trend approach, the counts are converted to logCPM values using edgeR’s cpm function: logCPM <- cpm(dge, log=TRUE, prior.count=3) prior.count is the constant that is added to all counts before log transformation in order to avoid taking the log of 0.
