Try one of a study's (or the company's) ARD functions — try_ard

In a separate R process, so a function that hangs or fails does not stop the app: loads the R files the study's ARD programs load (source, in their order; the company's file too when the study does not have the function), reads the data (a dataset of the ARD definition, of an analysis set; cards::ADSL when none is given), and runs tflspec::tfl_check_ard_function() with args as an analysis row would give them. The result is kept (programs/ard/functions/.checks.json).

Usage

try_ard_function(
  study,
  name,
  dataset = NA_character_,
  population_id = NA_character_,
  args = "",
  home = tflplanner_home(),
  timeout = 60
)

Arguments

study: An rtfstudy.
name: The function.
dataset, population_id: The data: a dataset of the ARD definition and an analysis set (either may be NA); both NA: cards::ADSL.
args: Its arguments as R ("by = TRT01A, variables = AGE").
home: The tflplanner home.
timeout: Seconds to allow.

Value

A list: problems (data frame: level, check, message), ard (the first rows of the ARD it gave, or NULL), error (when it could not be tried), seconds.
