Control Function for survfit Model for Survival Time

This is an auxiliary function for controlling arguments for survfit model, typically used internally to specify details of survfit model for s_surv_time. conf_level refers to survival time estimation.

Usage

control_surv_time(
  conf_level = 0.95,
  conf_type = c("plain", "log", "log-log"),
  quantiles = c(0.25, 0.75)
)

Arguments

conf_level: (proportion)
confidence level of the interval.
conf_type: (string)
"plain" (default), "log", "log-log" for confidence interval type,
see more in survival::survfit(). Note that the option "none" is no longer supported.
quantiles: (numeric)
of length two to specify the quantiles of survival time.

Value

A list of components with the same names as the arguments
