plot.survfit has an option for this

Eg, expanding on example(plot.survfit)

data(aml)
leukemia.surv <- survfit(Surv(time, status) ~ x, data = aml)
plot(leukemia.surv, lty = 2:3,fun="cloglog")


A couple of days ago Rob Gentleman found that this doesn't work if the
first observation is censored.  I will be putting up a revised survival5
soon, but I can send you the modified file for plot.survfit if necessary.
