\begin{Description}\relax
Probe-level and pre-proecssed data 
for six
arrays (two triplicates) from the HGU95 and HGU133 SpikeIn experiments.
\end{Description}
\begin{Usage}
\begin{verbatim}
data(spikein95)
data(rma95)
data(mas95)

data(spikein133)
data(rma133)
data(mas133)
\end{verbatim}
\end{Usage}
\begin{Format}\relax
\code{SpikeIn} is \code{\LinkA{ProbeSet}{ProbeSet}} containing the
$PM$ and $MM$ intensities for a gene spiked in at different
concentrations. Use \code{pData} to see the cosntrations.
\end{Format}
\begin{Source}\relax
\code{spikein95} and \code{spikein133} are instances of
\code{\LinkA{ProbeSet}{ProbeSet}} with the probe-level data
for six arrays (two triplicates) from the HGU95 and HGU133 SpikeIn
experiments respectively. \code{rma95} and \code{rma133} contain the
data pre-processed with RMA. \code{mas95} and \code{mas133} contain
the data preprocssed with mas5 (expression and present/absent
calls). The calls are in objects called \code{pacalls95} and
\code{pacalls133}.
