Retry a task (or set of tasks). Typically this is after failure
(e.g., ERROR, DIED or similar) but you can retry even
successfully completed tasks. Once retried, functions that
retrieve information about a task (e.g., rrq_task_status(), [rrq_task_result()]) will behave differently depending on the value of their followargument. Seevignette("fault-tolerance")` for more details.
rrq_task_retry(task_ids, controller = NULL)Task ids to retry.
The controller to use. If not given (or NULL)
we'll use the controller registered with
rrq_default_controller_set().
