Helper Functions for Constructing ADQLQC

Description

Internal functions used by radqlqc.

Usage

get_qs_data(
  adsl,
  visit_format = "CYCLE",
  n_assessments = 5L,
  n_days = 1L,
  lookup = NULL,
  seed = NULL,
  na_percentage = 0,
  na_vars = list(QSORRES = c(1234, 0.2), QSSTRESC = c(1234, 0.2))
)

get_random_dates_between(from, to, visit_id)

prep_adqlqc(df)

calc_scales(adqlqc1)

derv_chgcat1(dataset)

comp_derv(dataset, percent, number)

Arguments

adsl	(data.frame) Subject-Level Analysis Dataset (ADSL).
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").
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.
from	(⁠datetime vector⁠) Start date/times.
to	(⁠datetime vector⁠) End date/times.
visit_id	(vector) Visit identifiers.
df	(data.frame) SDTM QS dataset.
adqlqc1	(data.frame) Prepared data generated from the prep_adqlqc() function.
dataset	(data.frame) Dataset.
percent	(numeric) Completion - Completed at least y percent of questions, 1 record per visit
number	(numeric) Completion - Completed at least x question(s), 1 record per visit
