Description

A function performing MA transformation of data with replicates (for internal use).

Usage

1

Arguments

y

expression data with replicates per each condition

Details

For duplicate arrays (x1, x2), M=x1/x2 versus A=x1*x2 can facilitate the investigation of between-duplicate variability in terms of overall intensity.

Value

matrix

MA matrix

## Generating a replicated simulation dataset
simData <- generateData(n.deg=1000)

## Normalization
normData <- generateData(simData[,-7])

## MA transformation
MAdata4X <- am.trans(normData[,1:3])
MAdata4Y <- am.trans(normData[,4:6])
