Time-to-Event Analysis Dataset (ADTTE)

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.

Value

data.frame

Details

Keys: STUDYID, USUBJID, PARAMCD

Examples

adsl <- radsl(N = 10, seed = 1, study_duration = 2)
