Hi, I am trying to plot two distribution graph on one plot. But I dont know how. I set them to the same x, y limit, even same x, y labels. Code: x1=rnorm(25, mean=0, sd=1) y1=dnorm(x1, mean=0, sd=1) x2=rnorm(25, mean=0, sd=1) y2=dnorm(x2, mean=0, sd=1) plot(x1, y1, type='p', xlim=range(x1,x2), ylim=range(y1, y2), xlab='x', ylab='y') plot(x2, y2, type='p', col="red", xlab='x', ylab='y') They just dont show up in one plot. Any hint will be very helpful. Thanks, Yun

Thanks. Now R plots two graphs on one plot. Yet they are still on two graphs, vertically parallelized with each other. But what I want to do is actually plotting two distribution on one single graph, using the same x and y axis. Like: | | | (dist2) | (dist 1) | ---------------------------> Is it possible to do that?

Hi Yun, If you're asking how to place new graphic material on the same plot (e.g., several lines/points/etc in a single x-y region), this is covered in the Intro to R manual. E.g., you can do: plot(x1, y1, type='p', xlim=range(x1,x2), ylim=range(y1, y2), xlab='x', ylab='y') points(x2, y2, col="red") see ?lines ?points ?text ?abline Also, see the "new" option in par Best, Matt On 2/23/07, Yun Zhang <yunzhang at princeton.edu> wrote:> Hi, > > I am trying to plot two distribution graph on one plot.

Hi Yun,
try this.
x1 <- rnorm(10000, 0.5,0.4018)
x2 <- rnorm(10000, 0.01919,0.3969)
d1 <- density(x1)
d2 <- density(x2)
plot(range(d1$x,d2$x), range(d1$y, d2$y), type "n",
xlab = "X", ylab = "Y" )
lines(d1, col = "blue",lwd=2)
lines(d2, col = "red",lwd=2)
Cheers
Nguyen
