WebMethods. 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.
