\begin{Description}\relax
Container for high-throughput assays and experimental
metadata. \code{SnpSet} class is derived from
\code{\LinkA{eSet}{eSet}}, and requires matricies \code{call},
\code{callProbability} as assay data members.
\end{Description}
\begin{Section}{Extends}
Directly extends class \code{\LinkA{eSet}{eSet}}.
\end{Section}
\begin{Section}{Creating Objects}
\code{new('SnpSet',
    phenoData = [AnnotatedDataFrame],
    experimentData = [MIAME],
    annotation = [character],
    call = [matrix],
    callProbability = [matrix],
    ...)
  }

\code{SnpSet} instances are usually created through
\code{new("SnpSet", ...)}. Usually the arguments to \code{new}
include \code{call} (a matrix of gentoypic calls, with features (SNPs)
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.
\end{Section}
\begin{Section}{Slots}
Inherited from \code{eSet}:
\describe{
\item[\code{assayData}:] Contains matrices with equal
dimensions, and with column number equal to
\code{nrow(phenoData)}. \code{assayData} must contain a matrix
\code{call} with rows represening features (e.g., SNPs)
and columns representing samples, and a matrix
\code{callProbability} describing the certainty of the
call. The content of \code{call} and \code{callProbability} are
not enforced by the class. Additional matrices of
identical size may also be included in
\code{assayData}. Class:\code{\LinkA{AssayData-class}{AssayData.Rdash.class}}

\item[\code{experimentData}:] See \code{\LinkA{eSet}{eSet}}
\item[\code{annotation}:] See \code{\LinkA{eSet}{eSet}}
}
\end{Section}
\begin{Section}{Methods}
Class-specific methods:
\describe{
\item[\code{exprs(SnpSet)}, \code{exprs(SnpSet,matrix)<-}] Access and
set elements named \code{call} in the \code{AssayData}
slot.
}

Standard generic methods:
\describe{
\item[\code{initialize(SnpSet)}:] Object instantiation, used by \code{new}; not to be called directly by the user.
\item[\code{validObject(SnpSet)}:] Validity-checking method, ensuring that \code{call} and \code{callProbability} is a member of \code{assayData}. \code{checkValidity(SnpSet)} imposes this validity check, and the validity checks of \code{eSet}.
