}
\description{

}
\usage{
\method{summary}{rpart}(object, cp=0, digits=getOption("digits"), file, \dots)
}
\arguments{
\item{object}{
fitted model object of class \code{rpart}. This is assumed to be the result
of some function that produces an object with the same named
components as that returned by the \code{rpart} function.
}
\item{digits}{
Number of significant digits to be used in the result.
}
\item{cp}{
trim nodes with a complexity of less than \code{cp} from the listing.
}
\item{file}{
write the output to a given file name. (Full listings of a tree are
often quite long).
}
\item{\dots}{
arguments to be passed to or from other methods.
}}
\details{
This function is a method for the generic function summary for class
\code{"rpart"}. It can be invoked by calling \code{summary}
for an object of the appropriate class, or directly by calling
\code{summary.rpart} regardless of the class of the object.
