\begin{Description}\relax
Container for high-throughput assays and experimental
metadata. \code{MutliSet} is derived from
\code{\LinkA{eSet-class}{eSet.Rdash.class}}. \code{MultiSet} differs from
\code{\LinkA{ExpressionSet-class}{ExpressionSet.Rdash.class}} because \code{MultiSet} can contain
any element(s) in \code{assayData} (\code{ExpressionSet} must have an
element named \code{exprs}).
\end{Description}
\begin{Section}{Extends}
Directly extends class \code{\LinkA{eSet}{eSet}}.
\end{Section}
\begin{Section}{Creating Objects}
\code{new('MultiSet',
    phenoData = [AnnotatedDataFrame],
    experimentData = [MIAME],
    annotation = [character],
    ...)
  }

\code{updateOldESet(oldESet,"MultiSet")}

\code{MultiSet} instances are usually created through
\code{new("MultiSet", ...)}. The \code{...} arguments to \code{new}
are matrices of expression data (with features
corresponding to rows and samples to columns), \code{phenoData},
\code{experimentData}, and \code{annotation}. 
\code{phenoData}, \code{experimentData}, and \code{annotation} can be
missing, in which case they are assigned default values.

\code{\LinkA{updateOldESet}{updateOldESet}} will take a serialized instance (e.g., saved to a disk
file with \code{save} object created with earlier definitions of
the \code{eSet-class}, and update the object to
\code{MultiSet}. Warnings are issued when direct translation is not
possible; incorrectly created \code{oldESet} instances may not be updated.

\begin{Section}{Slots}
Inherited from \code{eSet}:
\describe{
\item[\code{assayData}:] Contains zero or more matrices with equal
dimensions, and with column number equal to
\code{nrow(phenoData)}. Each matrix in \code{assayData} has rows
represening features (e.g., reporters) and columns representing
samples. Class:\code{\LinkA{AssayData-class}{AssayData.Rdash.class}}
