Intensity data for 1 cDNA slide with two adjacent tissue samples
from a nephrectomy (kidney)
\end{Description}
\begin{Usage}
\begin{verbatim}data(kidney)\end{verbatim}
\end{Usage}
\begin{Format}\relax
\code{kidney} is an
\code{\LinkA{ExpressionSet}{ExpressionSet}}
containing the data from one cDNA
chip. The 8704x2 matrix \code{exprs(kidney)} contains the
spot intensities for the red (635 nm) and green color channels
(532 nm) respectively. For each spot, a background estimate from a
surrounding region was subtracted.
\end{Format}
\begin{Details}\relax
The chip was produced in 2001 by Holger Sueltmann at
the Division of Molecular Genome Analysis at the German Cancer
Research Center in Heidelberg.
