plot survival points

Hi Thomas
I try it, but the graphic make is not a point graphic, is a ?scale? plot,
like this:

|_
| |_
|   |
|   |__
|      |_
|        |_
|_____________

I need the same graphic, but with point like this:

|
| *
|   *
|   *
|       *
|         *
|____________

Here's an example of superimposing points on lines for two groups

library(survival)
data(aml)
#fitted exponential models
curve(1-pexp(x,rate=0.04314),col="green",from=0,to=150)
curve(1-pexp(x,rate=0.01655),col="blue",from=0,to=150,add=TRUE)
 fit <- survfit(Surv(time, status) ~ x, data = aml)
 points(fit[1],col="blue")
 points(fit[2],col="green")
