Control function for survfit models for patients' survival rate at time points

This is an auxiliary function for controlling arguments for survfit model, typically used internally to specify details of survfit model for s_surv_timepoint(). conf_level refers to patient risk estimation at a time point.

Usage

control_surv_timepoint(
  conf_level = 0.95,
  conf_type = c("plain", "log", "log-log")
)

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.

Value

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