\alias{mona.object}
\title{Monothetic Analysis (MONA) Object}
\description{
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{\link{mona}}.
}
\section{METHODS}{
The \code{"mona"} class has methods for the following generic functions:
\code{print}, \code{summary}, \code{plot}.
}
\value{
A legitimate \code{mona} object is a list with the following components:
\item{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{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{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{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{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.
}
}
