I have been trying to use the censored bootstrap function 'censboot'  from the library boot, with the function 'survfit' from the library  survival. I get the error message: 

In min(surv$time[inds[1 - surv$surv[inds] >= 0.5]]) ... :
  no non-missing arguments to min; returning Inf

Does anyone know what this means, or what I'm doing wrong? Thank you very much.
