Get the result for a single task (see rrq_task_results for a method for efficiently getting multiple results at once). Returns the value of running the task if it is complete, and an error otherwise.
rrq_task_result(task_id, error = FALSE, follow = NULL, controller = NULL)The single id for which the result is wanted.
Logical, indicating if we should throw an error if a
task was not successful. By default (error = FALSE), in the
case of the task result returning an error we return an object
of class rrq_task_error, which contains information about the
error. Passing error = TRUE calls stop() on this error if it
is returned.
Optional logical, indicating if we should follow any
redirects set up by doing rrq_task_retry. If not given, falls
back on the value passed into the controller, the global option
rrq.follow, and finally TRUE. Set to FALSE if you want to
return information about the original task, even if it has been
subsequently retried.
The controller to use. If not given (or NULL)
we'll use the controller registered with
rrq_default_controller_set().
