\title{Retrieve feature and sample names from eSets.}
\description{
These generic functions access the feature names (typically, gene or SNP
identifiers) and sample names stored in an object derived from the

}
\usage{
featureNames(object)
featureNames(object) <- value
sampleNames(object)
sampleNames(object) <- value
}
\arguments{
\item{object}{Object, possibly derived from class \code{eSet}.}
\item{value}{Character vector containing feature or sample names.}
}
\value{
\code{featureNames} returns a (usually long!) character vector
uniquely identifying each feature.\code{sampleNames} returns a
(usually shorter) character vector identifying samples.
