[R] Simulating survival data

[Peter Tait]

Hi Dr.Harrell,
thanks for the tip but I am not sure Quantile2() does what I'm need.
I need to repeatedly simulate 30 day survival data with a given sample 
size and estimate a hazard ratio for each simulated data set. I want to 
create a 95%CI for the hazard ratio by creating a distribution for it at 
different sample sizes.
 From reading the documentation and running the examples,  Quantile2() 
does not appear to do what I need.
Please correct me if I'm wrong.
Cheers
Peter
