   \item{dataPrecision}{default NULL, permits rounding of the interval endpoints (added by Richard Dunlap). The data precision used for printing interval values in the legend returned by \code{findColours}, and in the \code{print} method for classIntervals objects. If intervalClosure is \dQuote{left}, the value returned is \code{ceiling} of the data value multiplied by 10 to the dataPrecision power, divided by 10 to the dataPrecision power. The argument does not round \code{var}, the input variable.}
