 Hello R users !

Here a survfit object :

library(survival)

essai <- aml[aml$x == "Maintained",]

calc <- survfit(Surv(essai$time, 1 - essai$status))

calc

Call: survfit(formula = Surv(essai$time, 1 - essai$status))

      n  events  median 0.95LCL 0.95UCL
     11       4     103      28     Inf

I would like to get the median of the object "calc"... For example,

med <- calc$median

But it doesn't work... How can I do this ?
