Hi all, I have a basic question. how can i visualize two or more density curves on the same plot? ex: x1<-runif(100,10,80) x2<-runif(100,1,100) kernelgraf<-density(x1,kernel = "gaussian", width= 20) plot(kernelgraf, xlab="Probability", xlim=c(0,100), ylim=c(0,.1), col=rgb(0,1,0), main="") kernelgraf<-density(x2,kernel = "gaussian", width= 20) points(kernelgraf, xlab="Probability", xlim=c(0,100), ylim=c(0,.1), col=rgb(0,0,1), main="") here i am using plot + points, but i do not like the graphical output for points.
You are almost there, replace your last command by : points(kernelgraf, type="l", col="blue") Romain PS : Maybe a function points.density setting type="l" would be a good thing ?
Or maybe use lines(kernelgraf, type="l", col="blue") As I always say, when you want lines, use lines(). Duncan Murdoch
can anybody help me? thanks in advance Roberto Furlan University of Turin
