Hello, In package survival should be a dataset bladder1. http://stat.ethz.ch/R-manual/R-devel/library/survival/html/bladder.html I can not open it (not found).
In the documentation for my installation of survival, version 2.34-1, the help page only lists bladder and bladder2. Furthermore, executing data(bladder2) gives me a "data set'bladder2' not found" warning. Updating from source to 2.35-4 on the Mac does not improve the situation. The link to the help page you are offering is to the r-devel tree so perhaps this question should have gone to Dr. Lumley?
Both bladder and bladder2 are there.
You are luckier than I.
Thanks, Petra

David, You might want to try to exit from your R session and open a new one, or detach(package:survival) and then re-load: > library(survival) Loading required package: splines > str(bladder) 'data.frame': 340 obs. of 7 variables: $ id : int 1 1 1 1 2 2 2 2 3 3 ... $ rx : num 1 1 1 1 1 1 1 1 1 1 ... $ number: int 1 1 1 1 2 2 2 2 1 1 ... $ size : int 3 3 3 3 1 1 1 1 1 1 ... $ stop : int 1 1 1 1 4 4 4 4 7 7 ... $ event : num 0 0 0 0 0 0 0 0 0 0 ... $ enum : int 1 2 3 4 1 2 3 4 1 2 ... > str(bladder1) 'data.frame': 294 obs. of 11 variables: $ id : int 1 2 3 4 5 6 6 7 8 9 ... $ treatment: Factor w/ 3 levels "placebo","pyridoxine",..: 1 1 1 1 1 1 1 1 1 1 ... $ number : int 1 1 2 1 5 4 4 1 1 1 ... $ size : int 1 3 1 1 1 1 1 1 1 3 ... $ recur : int 0 0 0 0 0 1 1 0 0 1 ... $ start : int 0 0 0 0 0 0 6 0 0 0 ... $ stop : int 0 1 4 7 10 6 10 14 18 5 ... $ status : num 3 3 0 0 3 1 3 0 0 1 ... $ rtumor : chr "."
