\keyword{cluster}{mona.object}
\begin{Description}\relax
The objects of class \code{"mona"} represent the divisive
hierarchical clustering of a dataset with only binary variables
(measurements).   This class of objects is returned from
\code{\LinkA{mona}{mona}}.
\end{Description}
\begin{Value}
A legitimate \code{mona} object is a list with the following components:

\begin{ldescription}
\item[\code{data}] matrix with the same dimensions as the original data matrix,
but with factors coded as 0 and 1, and all missing values replaced.

\item[\code{order}] a vector giving a permutation of the original observations to allow
for plotting, in the sense that the branches of a clustering tree
will not cross.

\item[\code{order.lab}] a vector similar to \code{order}, but containing observation labels
instead of observation numbers. This component is only available if
the original observations were labelled.

\item[\code{variable}] vector of length n-1 where n is the number of observations,
specifying the variables used to separate the observations of \code{order}.

\item[\code{step}] vector of length n-1 where n is the number of observations,
specifying the separation steps at which the observations of
\code{order} are separated.

\end{ldescription}
\end{Value}
\begin{Section}{METHODS}
The \code{"mona"} class has methods for the following generic functions:
\code{print}, \code{summary}, \code{plot}.
