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. Assit. Prof. Meral YAY [[alternative HTML version deleted]]
