\title{
Functions to extract the components of a "baseline" object
}
\description{
The functions extract the \code{baseline}, \code{spectra},
\code{corrected} or \code{call} slot of a \code{\linkS4class{baseline}}
object; usually the result of a call to \code{\link{baseline}}.
}
\usage{
getBaseline(object)
getSpectra(object)
getCorrected(object)
getCall(object)
}
\arguments{
  \item{object}{A \code{\linkS4class{baseline}} object}
}
\value{
  \code{getCall} returns the \code{baseline} call used to create the
  object.  The other functions return a matrix with the original
  spectra, estimated baselines or corrected spectra.

\section{Warning}{In a future versoion, one of the slots might be
  removed from the class definition and calculated on the fly instead,
  in order to save space.  Therefore, \emph{do} use the extractor
  functions (\code{getSpectra}, \code{getBaseline} and
  \code{getCorrected}) instead of accessing the slots directly.}
