\begin{Description}\relax
Reads a comma delimeted file containing the expression values of the
dilution and spike-in data sets and creates a \code{\Link{exprSet}}
\end{Description}
\begin{Usage}
\begin{verbatim}
read.dilution(filename)
read.spikein(filename,cdfName=c("hgu95a","hgu133a")
read.newspikein(filename)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{filename}] character containing the filename to be read.
\item[\code{cdfName}] are we reading data from the hgu95a or hgu133a spike-in experiment?
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
The file to be read must be come delimeted with the first row
containing the cel fileneames (case sensitive). The first column must
be the Affymetrix gene identifiers. \code{read.dilution} will put
things in the right place.

\code{read.newspikein} is a wrapper to read results from the hgu133a
spikein experiment.\end{Details}
\begin{Value}
An \code{\Link{exprSet}}.\end{Value}
