Cancel a new branch

cellucid_history_branch_cancel.Rd

Forget the branch "Branch here" set to start with the next change.

Usage

cellucid_history_branch_cancel(viewer)

Arguments

viewer

A viewer cellucid_view() or cellucid_serve() returned.

Value

A cellucid_action_request, at once and invisibly: the action is sent now, or when the viewer's channel opens. cellucid_action_result(request) returns its outcome: a list of cancelled (The name forgotten; null when none was set).

Details

The viewer's action history.branch.cancel (History). It moves the viewer's history, as the person's Undo, Redo or a click on a step does: it makes no step of the history.

See also

cellucid_act() sends any action by its type, and cellucid_action_result() collects its answer.

Examples

if (interactive() && requireNamespace("SeuratObject", quietly = TRUE)) {
  data("pbmc_small", package = "SeuratObject")
  viewer <- cellucid_view(SeuratObject::UpdateSeuratObject(pbmc_small))
  request <- cellucid_history_branch_cancel(viewer)
  print(request)
  # cellucid_action_result(request) waits for its outcome.
  cellucid_stop(viewer)
}
