simple save question
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)

records n.max n.start events *rmean *se(rmean) median

> data(melanom)

> summary(cox.model)
Call:
coxph(formula = Surv(days, status == 1) ~ sex)
n= 205
coef exp(coef) se(coef) z p
sex 0.662 1.94 0.265 2.50 0....
