ProbeSet-class {affy} | R Documentation

## Class ProbeSet

### Description

A simple class that contains the PM and MM data for a probe set from one or more samples.

### Objects from the Class

Objects can be created by applying the method `probeset` to instances of AffyBatch.

### Slots

`id`:

  Object of class `"character"` containing the probeset ID.

`pm`:

  Object of class `"matrix"` containing the PM intensities. Columns represent samples and rows the different probes.

`mm`:

  Object of class `"matrix"` containing the MM intensities.

### Methods

colnames

  `signature(x = "ProbeSet")`: the column names of the `pm` matrices which are the sample names

express.summary.stat

  `signature(x = "ProbeSet", pmcorrect = "character", summary = "character")`: applies a summary statistic to the probe set.

sampleNames

  `signature(object = "ProbeSet")`: the column names of the `pm` matrices which are the sample names.
