\description{
The \emph{Leucine-responsive regulatory protein} (Lrp) is thought to regulate
the expression of multiple genes and operons in bacteria. Two strains
\emph{lrp+} and \emph{lrp-} were studied to investigate which genes are
subject to changes in expression levels.

The raw data were taken from CyberT website. The data for 8 chips (4
\emph{lrp+} and 4 \emph{lrp-}).
