This data package contains an \code{marrayRaw} instance for the as well
as 6 gpr files of the beta7 microarray experiment.

\usage{data(beta7)}
\details{Each arrays(hybridization) involved
\eqn{\beta 7+} cell RNA from a single subject (labeled with one dye) and
\eqn{\beta7-} cell RNA from the same subject (labeled with the other dye).
Target RNA was hybridized to microarrays containing 23,184 probes
including Operon Human version 2 set of 70-mer oligonucleotide probes and 1760
controls spots (e.g. negative, positive and normalization controls
spots).
