Examples

require(survival)

leukemia.surv <- survival::survfit(survival::Surv(time, status) ~ x, data = survival::aml)

qkmplot(leukemia.surv, conf_int = TRUE)

qkmplot_bulid_data_frame(leukemia.surv)

qrmst(leukemia.surv) # NaN for rmst.se in Nonmaintained strata as last observation is an event
qrmst(leukemia.surv, 44)

# pbc examples
pbc_fit <-
  survival::survfit(
      formula = survival::Surv(time, status > 0) ~ trt
    , data = pbc
    , subset = !is.na(trt)
  )

qkmplot(pbc_fit)
qkmplot(pbc_fit, conf_int = TRUE)

qrmst(pbc_fit)
qrmst(pbc_fit)
