Test if task ids exist (i.e., are known to this controller). Nonexistant tasks may be deleted, known to a different controller or just never have existed.
rrq_task_exists(task_ids, named = FALSE, controller = NULL)
Vector of task ids to check
Logical, indicating if the return value should be named with the task ids; as these are quite long this can make the value a little awkward to work with.
The controller to use. If not given (or NULL
)
we'll use the controller registered with
rrq_default_controller_set()
.
A logical vector the same length as task_ids; TRUE
where
the task exists, FALSE
otherwise.
