Hi,
When I run the survfit function, I want to get the restricted mean
value and the standard error also. I found out using the "print"
function to do so, as shown below,
print(km.fit,print.rmean=TRUE)
Call: survfit(formula = Surv(diff, status) ~ 1, type = "kaplan-meier")
records n.max n.start events *rmean *se(rmean) median
200.000 200.000 200.000 129.000 0.145 0.237 1.158
0.95LCL 0.95UCL
0.450 1.730
* restricted mean with upper limit = 2.97
The questions is, is there any way to extract these values from the
print command?
Thanks a lot.
