diffAnaComputeFDR {DAPAR} | R Documentation

## Computes the FDR corresponding to the p-values of the differential analysis using

### Description

This function is a wrappper to the function adjust.p from the cp4p package. It returns the FDR corresponding to the p-values of the differential analysis. The FDR is computed with the function `p.adjust`{stats}..

### Usage

    diffAnaComputeFDR(data, threshold_PVal = 0, threshold_LogFC = 0,
      pi0Method = 1)

### Arguments

`data` | The result of the differential analysis processed by `diffAna`
`threshold_PVal` | The threshold on p-pvalue to distinguish between differential and non-differential data
`threshold_LogFC` | The threshold on log(Fold Change) to distinguish between differential and non-differential data
`pi0Method` | The parameter pi0.method of the method adjust.p in the package `cp4p`

### Value

The computed FDR value (floating number)

### Examples

    require(DAPARdata)
    data(Exp1_R25_pept)
    obj <- wrapper.mvImputation(Exp1_R25_pept[1:1000], "QRILC")
    condition1 <- '25fmol'
    condition2 <- '10fmol'
    qData <- Biobase::exprs(obj)
    samplesData <- Biobase::pData(obj)
    labels <- Biobase::pData(obj)[,"Label"]
    limma <- diffAnaLimma(qData,samplesData, labels, condition1, condition2)
    diffAnaComputeFDR(limma)
