    meaningful.}

}
\value{
  Coefficients extracted from the model object \code{x}.
}
\description{
  \code{coef} is a generic function which extracts model coefficents
  from objects returned by modeling functions.  \code{coefficients} is
  an \emph{alias} (\code{\link{.Alias}}) for it.
}
\details{
  All object classes which are returned by model fitting functions
  should provide a \code{coef} method.  (Note that the method is \code{coef} and
  not \code{coefficients}.)
