normalize.quantiles.probeset {affyPLM} | R Documentation

## Quantile Normalization applied to probesets

### Description

Using a normalization based upon quantiles, this function normalizes a matrix of probe level intensities.

### Usage

      normalize.AffyBatch.quantiles.probeset(abatch,type=c("separate","pmonly","mmonly","together"),use.median=FALSE,use.log=TRUE)

### Arguments

`abatch` | An `AffyBatch`
`type` | how should MM and PM values be handled
`use.median` | use median rather than mean
`use.log` | take logarithms, then normalize

### Details

This function applies the quantile method in a probeset specific manner.

In particular a probeset summary is normalized using the quantile method and then the probes adjusted accordingly.

### Value

A normalized `AffyBatch`.
