## Gene expression, annotations and clinical data from the International Genomics Consortium

### Description

This dataset contains (part of) the gene expression, annotations and clinical data from the expO dataset collected by the International Genomics Consortium (http://www.intgen.org/expo/).

### Usage

    data(expos)

### Format

`expos` is a dataset containing three matrices:

data.expos

  Matrix containing gene expressions as measured by Affymetrix hgu133plus2 technology (single-channel, oligonucleotides

annot.expos

  Matrix containing annotations of ffymetrix hgu133plus2 microarray platform

demo.expos

  Clinical information of the breast cancer patients whose tumors were hybridized

### Details

This dataset has been generated by the International Genomics Consortium using Affymetrix hgu133plus2 technology. The gene expressions have been normalized using fRMA. Only part of the gene expressions (966) are contained in `data.expos`.
