Its usually not very menaingful except for \code{xyplot}. It just orders the absolute slopes and returns a value which when adjusted by the panel scale limits will make the median of the above absolute slopes a 45 degree line. } \author{ Deepayan Sarkar \email{deepayan@stat.wisc.edu}} \seealso{\code{\link{Lattice}}, \code{\link{xyplot}}} \keyword{dplot}
