## DAU test

### Description

Performs DAU test

### Usage

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

### Arguments

`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

### Value

an object of testDAUresults ready for plotting

### Examples

        data("seq.example")
        data("proteome.example")
        bg <- buildBackgroundModel(seq.example, proteome=proteome.example)
        t <- testDAU(seq.example, bg, bgNoise=0.05)
