Add a Job

Description

Inform RStudio's Background Jobs pane that a job has been added.

Usage

jobAdd(
  name,
  status = "",
  progressUnits = 0L,
  actions = NULL,
  running = FALSE,
  autoRemove = TRUE,
  show = TRUE
)

Arguments

name	The background job's name.
status	The initial status text for the job; optional.
progressUnits	The integer number of units of work in the job; for example, 100L if the job's progress is expressed in percentages. Use 0L if the number of units of work is unknown.
actions	A list of actions that can be performed on the job (see Actions).
running	Whether the job is currently running.
autoRemove	Whether to remove the job from the Background Jobs pane when it's complete.
show	Whether to show the job in the Jobs pane.

Value

An ID representing the newly added job, used as a handle to provide further updates of the job's status.

Actions

The actions parameter is a named list of functions that the user can invoke on the job; for example: actions = list(stop = function(id) { ... }). The function will be passed a parameter named id with the job ID that invoked it.

There are three special action names:

stop

If there is an action named stop, then the job will have a Stop button in in the Jobs pane, and pressing that button will invoke the stop action.

info

If there is an action named info, then the job will have an informational link in the Background Jobs pane rather than an output display, and clicking the link will invoke the info action.

replay

If there is an action named replay, then the job will have a Replay button that displays when the job has finished running. Clicking the button will invoke the replay action.
