\title{Get a subset of arrays from an affybatch object, split by phnotypic data}
\description{
  Looks at a factor in the phenotypic data for an \code{AffyBatch} or \code{ExpressionSet} object and
  uses it to select a subset of arrays, as defined by 'members'.
}


\usage{
get.array.subset(x,group,members)
}

\arguments{
  \item{x}{An \code{ExpressionSet} or \code{AffyBatch} object.}
