Hi If you went through help page you probably could find it yourself in shorter time then you spend writing email and waited for others to write back.
see ?plot.stepfun > Dear all, > I would like to plot under the same plot > many curves like > > mycdf<-ecdf(runif(100)) > plot(mycdf) > curve(mycdf,from=-1,to=1) Why curve? Isn't plot enough? > > > mycdf<-ecdf(runif(200)+3) > plot(mycdf) > curve(mycdf,from=-1,to=1) Actually the value for mycdf in required interval is zero. To see the line you need to extend x and not to redraw the plot is ensured by add=TRUE. mycdf<-ecdf(runif(100)) plot(mycdf) curve(mycdf,from=-1,to=4) mycdf<-ecdf(runif(200)+3) curve(mycdf,add=TRUE, from=-1,to=4, col=2) Regards Petr > > as you can see each new call to curve redraws (erases) the window.
