testDAU(dagPeptides, dagBackground, 
                    group=c("null", "classic", "charge", "chemistry", "hydrophobicity"),
                    bgNoise=NA)

`dagPeptides`	an object of dagPeptides, output of `fetchSequence` or f`formatSequence`
`dagBackground`	an object of dagBackground, output of `buildBackgroundModel`
`group`	could be "null", "classic", "charge", "chemistry", "hydrophobicity"
`bgNoise`	if it is not NA, test will using a background by Dirichlet(1)-distributed random frequencies with weight bg.noise. The value of bgNoise should be a number in the range of 0 to 1, eg. 0.05

an object of testDAUresults ready for plotting
