16 fitDOfitDOWrapper to calculate Discovery Odds Ratios on feature values.DescriptionThis function returns a data frame of p-values, odds ratios, lower and upper confidence limits forevery row of a matrix. The discovery odds ratio is calculated as using Fisher’s exact test on actualcounts. The test’s hypothesis is whether or not the discovery of counts for a feature (of all counts)is found in greater proportion in a particular group.UsagefitDO(obj, cl, norm = TRUE, log = TRUE)ArgumentsobjclnormlogA MRexperiment object with a count matrix, or a simple count matrix.Group comparisonWhether or not to normalize the counts - if MRexperiment object.Whether or not to log2 transform the counts - if MRexperiment object.ValueNASee AlsocumNorm fitZigExamplesdata(lungData)k = grep("Extraction.Control",pData(lungData)$SampleType)lungTrim = lungData[,-k]lungTrim = lungTrim[-which(rowSums(MRcounts(lungTrim)>0)
