\section{Methods}{
  \describe{
    \item{plot}{\code{signature(x = "RFempVariog")}: gives a plot of the
      empirical variogram, for more details see
      \command{\link{plot-method}}.}
    \item{as}{\code{signature(x = "RFempVariog")}:
      converts into other formats, only implemented for target class
      \code{\link[methods:list-class]{list}}.}
    \item{show}{\code{signature(x = "RFfit")}: returns the structure
      of \code{x}}
    \item{persp}{code{signature(obj =
	"RFempVario")}: generates nice \command{\link[graphics]{persp}} plots
    }
    \item{print}{\code{signature(x = "RFfit")}: identical with
      \command{show}-method}
   \item{summary}{provides a summary}
  }
}


\section{Details}{
  \command{print} returns also an invisible list that is convenient to access.
