\title{Class DataTreeSet}
\description{This class provides the link to the \code{\link{ROOT}} data file and 
the \code{\link{ROOT}} trees contained therein. It extends class \code{\link{ProcesSet}}.}
\section{Objects from the Class}{
Objects can be created using the functions \code{\link{import.data}} or \code{\link{root.data}}.
}
