\title{Retrieve expression data from eSets.}
\description{
These generic functions access the expression and error measurements
of assay data stored in an object derived from the \code{\link{eSet-class}}.
}
\usage{
exprs(object)
exprs(object) <- value
se.exprs(object)
se.exprs(object) <- value
}
\arguments{
\item{object}{Object derived from class \code{eSet}.}
\item{value}{Matrix with rows representing features and columns samples.}
}
\value{
\code{exprs} returns a (usually large!) matrix of expression values;
\code{se.exprs} returns the corresponding matrix of standard errors,
when available.
