SpikeIn {SpikeInSubset} | R Documentation

## Subset of Affymetrix SpikeIn Experiment Data

### Description

Probe-level and pre-proecssed data for six arrays (two triplicates) from the HGU95 and HGU133 SpikeIn experiments.

### Usage

    data(spikein95)
    data(rma95)
    data(mas95)

    data(spikein133)
    data(rma133)
    data(mas133)

### Format

`SpikeIn` is `ProbeSet` containing the $PM$ and $MM$ intensities for a gene spiked in at different concentrations. Use `pData` to see the cosntrations.

### Source

`spikein95` and `spikein133` are instances of `ProbeSet` with the probe-level data for six arrays (two triplicates) from the HGU95 and HGU133 SpikeIn experiments respectively. `rma95` and `rma133` contain the data pre-processed with RMA. `mas95` and `mas133` contain the data preprocssed with mas5 (expression and present/absent calls). The calls are in objects called `pacalls95` and `pacalls133`.
