Thanks very much Achim! I was indeed using "pec" which requires "rms"...
I see now that the old version of pec that I used didn't require rms and therefore I had no problem.. I'm guessing I don't need the rms methods for my use of pec, but am not sure how I can remove the dependency or alternatively mask back the "Surv" object to survival package. Any ideas for that? Thanks again!
