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.

Xueke
