Control function for survfit models 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)
confidence interval type. Options are "plain" (default), "log", "log-log", see more in survival::survfit(). Note option "none" is no longer supported.

quantiles

(numeric(2))
vector of length two specifying the quantiles of survival time.

Value

A list of components with the same names as the arguments.
