\title{Class "specc"}
\description{ The Spectral Clustering Class}
\section{Objects from the Class}{
Objects can be created by calls of the form \code{new("specc", ...)}.
    or by calling the function \code{specc}. 
}
\section{Slots}{
  \describe{
    \item{\code{cluster}:}{Object of class \code{"vector"} containing
      the cluster to which each point is allocated}
    \item{\code{centers}:}{Object of class \code{"matrix"} containing
      the cluser centers}
    \item{\code{size}:}{Object of class \code{"vector"} containing the
      number of points in each  cluster}
    \item{\code{kernelf}}{Object of class \code{kernel} containing the
      used kernel function.}
  }
}
\section{Methods}{
  \describe{
    \item{centers}{\code{signature(object = "specc")}: returns the
      cluster centers}
    \item{cluster}{\code{signature(object = "specc")}: returns the
      cluster to which each point is allocated}
    \item{size}{\code{signature(object = "specc")}: returns the number
      of points in each cluster }
