plot.e <- function(b, w, x, y, z){ a <- window.chron(b, w, x, y, z) low <- min(b*0.98)+5 high <- max(b*1.02)+5 plot(a, ylim=c(low, high)) lines(a*0.98, col="blue") lines(a*1.02, col="red") } plot.e(day, "03/28/2007", "00:00:00", "03/28/2007", "23:46:00") why do the low and high objects not set the ylim of the plotting function? thanks -- Stephen Sefick Let's not spend our time and resources thinking about things that are so little or so large that all they really do for us is puff us up and make us feel like gods. We are mammals, and have not exhausted the annoying little problems of being mammals. -K.
