Time-to-Event Analysis Dataset (ATE) — radtte • random.cdisc.data

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

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

Subject-Level Analysis Dataset (ADSL).

event.descr

Character vector with description of events.

censor.descr

censor description.

lookup

Data.frame containing additional parameters.

seed

Seed for random number generation.

na_percentage

(numeric) 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 The seed to be used for this element - can be left NA
percentage How many element should be replaced. 0 is 0 % 1 is 100 %, can be left NA and default percentage is used. This will overwrite default percentage (percentage argument))

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
