\title{Subclasses of van't Veer breast cancer microarray data set}
\description{
  Microarray data from Broad
  Institute \dQuote{Cancer Program Data Sets} which
  was produced by van't Veer et al. 2002.
  Array S54 was removed because it is an
  outlier.

  Goal was to find a gene signature to predict
  the outcome of a cancer therapy that
  is to predict whether metastasis will occur.
  A 70 gene signature has been discovered.

  Here we want to find subclasses in the data set.

  Hoshida et al. 2007 found 3 subclasses and verified
  that 50/61 cases from class 1 and 2 were ER positive
  and only in 3/36 from class 3.

  \code{XBreast} is the data set with
  97 samples and 1213 genes,
  \code{CBreast} are the
  three subclasses from Hoshida et al. 2007.

\usage{CBreast}
\format{ Vector \code{CBreast} of 97 samples giving the 
  three subclasses from Hoshida.}
