\title{Sugeno integral}
\description{Computes the Sugeno integral of a \bold{non negative} function with
respect to a game. Moreover, if the game is a capacity, the range of the function must be contained into
the range of the capacity. The game can be given either under the form of an
object of class \code{game}, \code{card.game} or \code{Mobius.game}.}

\describe{
\item{object = "Mobius.game", f = "numeric" }{The Sugeno integral of
\code{f} is computed from the \enc{M—bius}{Mobius} transform of a game.}
\item{object = "game", f = "numeric" }{The Sugeno integral of \code{f}
is computed from a game.}
\item{object = "card.game", f = "numeric" }{The Sugeno integral of
\code{f} is computed from a cardinal game.}
