List stale results

cellucid_history_stale.Rd

Steps whose result no longer matches its inputs (the cells, the mapping, a highlight changed since), each with the step that made it stale and why.

Usage

cellucid_history_stale(viewer, tracker)

Arguments

viewer

A viewer cellucid_view() or cellucid_serve() returned.

tracker

A tracker by its name or its id (history_summary lists them); the tracker in use when left out. Text (at least 1 character). Left out unless given (the viewer then chooses as its own control does).

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 what it read: a list of stale, tracker. Cells in it are original positions (0-based rows of the dataset's obs).

Details

The viewer's action history.stale (History). It reads, and changes nothing: it makes no step of the history.

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_stale(viewer)
  print(request)
  # cellucid_action_result(request) waits for what it read.
  cellucid_stop(viewer)
}
