\begin{Description}\relax
Looks at a factor in the phenotypic data for an \code{AffyBatch} or \code{exprSet} object and
uses it to select a subset of arrays, as defined by 'members'.

\begin{verbatim}
get.array.subset(x,group,members)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{x}] An \code{ExpressionSet} or \code{AffyBatch} object 
\item[\code{group}] The name of the pData column to use. 
\item[\code{members}] The labels within the pData column to match against.
