\title{Class "superclass.set.func"}

\description{Virtual class, superclass of all \code{*.set.func} classes. Used to define common \code{show} and \code{summary} methods for \code{*.set.func} classes.}

\section{Objects from the Class}{A virtual Class: No objects may be created from it.}

\section{Slots}{
   \describe{
     \item{\code{n}:}{Object of class \code{numeric} of length 1 equal
       to the number of elements of the set on which the
       set function is defined.}
     
     \item{\code{data}:}{Object of class \code{numeric} containing the
       coefficients of the set function.}
    
  }
}
\section{Methods}{
  \describe{
    \item{show}{\code{signature(object = "superclass.set.func")} }
    \item{rnd}{\code{signature(x = "superclass.set.func", digits = "numeric")} }

## three set functions
mu1 <- card.set.func(-2:4)
mu2 <- set.func(c(-2,-2,-2:11/11))
mu3 <- Mobius.set.func(c(-7:6,6,6),4,4)

## print mu1
show(mu1)
## the same

## the others

## round mu2
