\title{
  Class to Contain Objects Describing High-Throughput SNP Assays.
}

\description{
  Container for high-throughput assays and experimental
  metadata. \code{SnpSet} class is derived from
  \code{\link{eSet}}, and requires matricies \code{call},
  \code{callProbability} as assay data members.  } \section{Extends}{
   Directly extends class \code{\link{eSet}}.
}
\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.
}
\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{\link{AssayData-class}}}
