\title{Microarry Data from St.Jude Children Research Hospital (USA)}
\description{
    Example for list-structure used by many functions in MACAT. It's based
    on the gene expression data published by Yeoh et al. in 2002.[Yeoh et al. Classification, 
    subtype discovery, and prediction of outcome in pediatric acute 
    lymphoblastic leukemia by gene expression profiling. Cancer Cell. 
    March 2002. 1: 133-143. The data has been preprocessed using 'vsn' on
    probe level and the probes have been summed up using 'median polish'.

\format{
 List of class 'MACATData' with 6 components:
 \describe{
    \item{geneName:}{Identifiers of genes/probe sets in expression data}
    \item{geneLocation:}{Location of genes on their chromosome as distance from
    5'end in base pairs Negative numbers denote genes on the antisense strand.}
    \item{chromosome:}{Chromosome of the respective gene. Components 'geneName',
    'geneLocation', and 'chromosome' are in the same order.}
    \item{expr:}{expression matrix with rows = genes and columns = samples/patients}
    \item{labels:}{(disease) subtype of each sample, has length = number of columns
    of expression matrix}
    \item{chip:}{Identifier for Microarray used for the experiments (here for the
    Affymetrix HG-U95av2 Oligonucleotide GeneChip)}
    }
