The computations done by print.survfit are now a part of the results returned by summary.survfit. See 'table' in the output list of ?summary.survfit. Both call an internal survmean() function...

Hi, I'm sure this should be simple but I can't figure it out! I want to get the median survival calculated by the survfit function and use the value rather than just be able to print it. Something like this: library(survival) data(lung) lung.byPS = survfit(Surv (time, status) ~ ph.ecog, data=lung) # lung.byPS Call: survfit(formula = Surv(time, status) ~ ph.ecog, data = lung) 1

hi I have a problem with  Median in Survival. when I use S1=survfit(Surv(Time,Status)) the result shows the median but I cannot use it as numeric! S1$median in Null   Could u pleas help me. Many Many Tank You. Niloofar. [[alternative HTML version deleted]]
