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 fformatSequence

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
