}
\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.
