radqs: Questionnaires Analysis Dataset (ADQS)

Description

Function for generating a random Questionnaires Analysis Dataset for a given Subject-Level Analysis Dataset.

Usage

radqs(
  adsl,
  param = c("BFI All Questions", "Fatigue Interference",
    "Function/Well-Being (GF1,GF3,GF7)", "Treatment Side Effects (GP2,C5,GP5)",
    "FKSI-19 All Questions"),
  paramcd = c("BFIALL", "FATIGI", "FKSI-FWB", "FKSI-TSE", "FKSIALL"),
  visit_format = "WEEK",
  n_assessments = 5L,
  n_days = 5L,
  seed = NULL,
  na_percentage = 0,
  na_vars = list(LOQFL = c(NA, 0.1), ABLFL2 = c(1234, 0.1), ABLFL = c(1235, 0.1), CHG2 =
    c(1235, 0.1), PCHG2 = c(1235, 0.1), CHG = c(1234, 0.1), PCHG = c(1234, 0.1)),
  cached = FALSE
)

Value

data.frame

Arguments

adsl

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

param

(character vector)
Parameter values.

paramcd

(character vector)
Parameter code values.

visit_format

(character)
Type of visit. Options are "WEEK" and "CYCLE".

n_assessments

(integer)
Number of weeks or cycles.

n_days

(integer)
Number of days in each cycle (only used if visit_format is "CYCLE").

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 ADQS data cadqs should be returned or new data should be generated. If set to TRUE then the other arguments to radqs will be ignored.
