\title{Class "game"}
\description{Class representing a game, i.e. a set function vanishing at
the empty set (also called \emph{non monotonic fuzzy measure}).}
\section{Objects from the Class}{Objects can be created by calls to the function \code{game}.}
\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 game is defined.}
\item{\code{subsets}:}{Object of class \code{numeric} of length
\code{2^n} containing the power set of the underlying set in
"natural" order. The subsets are coded as integers.}
\item{\code{data}:}{Object of class \code{numeric} of length
\code{2^n} containing the coefficients of the game in binary
order. We necessarily have \code{data[1] = 0}.}
}
}
\section{Extends}{
Class \code{set.func}, directly.
Class \code{superclass.set.func}, by class \code{set.func}.

## a game (which is a capacity)
mu <- game(c(0,rep(1,15)))
## the attributes of the object

## a conversion

## a transformation
Mobius(mu)
## let us check ...
