[clintval]

From early commit of README.md:

limma and edgeR need to be ported.
The dependency graphs for those libraries should be used as well.

It goes more or less like this:
design = model.matrix( ~ 0 + group, data=DGElist$samples) #design
DGElist = estimateCommonDisp(DGElist, verbose=TRUE) #statistics function 1
DGElist = estimateTagwiseDisp(DGElist) #statistics function 2
v <- voom(d.cpm.x, design, plot=TRUE) #statistics function 3
