Usage

assert_gp3ml_use_case(task, data = NULL)

Arguments

task: A gp3ml_task object.
data: Optional data frame used to validate task columns.

Value

Invisibly returns TRUE when the task is permitted; otherwise, the function stops with an error.

Examples

  participant_id = rep(sprintf("P%02d", 1:12), each = 2),
  trial_id = sprintf("T%02d", 1:24),
  stimulus_id = rep(c("S01", "S02"), 12),
  condition = rep(c("A", "B"), 12),
  fixation_duration = 180 + seq_len(24),
  pupil_change = sin(seq_len(24) / 3),
  stringsAsFactors = FALSE
