Yes, it is a bug. Thanks for providing a complete example. I'll look into it, but leave for a week's vacation in a couple of hours and have some other pressing tasks. Terry T. Terry, I recently noticed the censor argument of survfit. For some analyses it greatly reduces the size of the resulting object, which is a nice feature. However, when combined with the id argument, only 1 prediction is made. Predictions can be made individually but I'd prefer to do them all at once if that change can be made. Chris
