\title{Function to apply lowess normalization to an expression set.}
\description{
Like \code{\link{lnorm}}, but applies to and returns an \code{ExpressionSet} or \code{AffyBatch} object instead of a \code{matrix}.
}
\usage{
lnormeS(eS, span=0.1)
}
\arguments{
  \item{eS}{ An \code{ExpressionSet} or \code{AffyBatch} object}
  \item{span}{Smoothing parameter for lowess.  Larger values correspond to more smoothness.}
}
\value{
Returns an \code{ExpressionSet} with \code{exprs(eS)} normalized by \code{\link{lnorm}}.
