radtte {random.cdisc.data}

Time-to-Event Analysis Dataset (ADTTE)

Description

Function for generating a random Time-to-Event Analysis Dataset for a given Subject-Level Analysis Dataset.

Usage

radtte(
  adsl,
  event_descr = NULL,
  censor_descr = NULL,
  lookup = NULL,
  seed = NULL,
  na_percentage = 0,
  na_vars = list(CNSR = c(NA, 0.1), AVAL = c(1234, 0.1), AVALU = c(1234, 0.1)),
  cached = FALSE
)

Arguments

adsl

(data.frame)
Subject-Level Analysis Dataset (ADSL).

event_descr

(⁠character vector⁠)
Descriptions of events. Defaults to NULL.

censor_descr

(⁠character vector⁠)
Descriptions of censors. Defaults to NULL.

lookup

(data.frame)
Additional parameters.

seed

(numeric)
Seed to use for reproducible random number generation.

na_percentage

(proportion)
Default percentage of values to be replaced by NA.

na_vars

(list)
A named list where the name of each element is a column name of ds. Each element of this list should be a numeric vector with two elements:

• seed (numeric)
  The seed to be used for this element - can be NA.

• percentage (proportion)
  Percentage of elements to be replaced with NA. If NA, na_percentage is used as a default.

cached

boolean whether the cached ADTTE data cadtte should be returned or new data should be generated. If set to TRUE then the other arguments to radtte will be ignored.
