Use tar_watch_ui() and tar_watch_server() to include tar_watch() as a Shiny module in an app.

tar_watch_ui(
  id,
  label = "tar_watch_label",
  seconds = 10,
  seconds_min = 1,
  seconds_max = 60,
  seconds_step = 1,
  targets_only = FALSE,
  outdated = FALSE,
  label_tar_visnetwork = NULL,
  level_separation = 150,
  degree_from = 1L,
  degree_to = 1L,
  height = "650px",
  display = "summary",
  displays = c("summary", "branches", "progress", "graph", "about")
)

Arguments

id

Character of length 1, ID corresponding to the UI function of the module.

label

Label for the module.

seconds

Numeric of length 1, default number of seconds between refreshes of the graph. Can be changed in the app controls.

seconds_min

Numeric of length 1, lower bound of seconds in the app controls.

seconds_max

Numeric of length 1, upper bound of seconds in the app controls.

seconds_step

Numeric of length 1, step size of seconds in the app controls.

targets_only

Logical, whether to restrict the output to just targets (FALSE) or to also include global functions and objects.

outdated

Logical, whether to show colors to distinguish outdated targets from up-to-date targets. (Global functions and objects still show these colors.) Looking for outdated targets takes a lot of time for large pipelines with lots of branches, and setting outdated to FALSE is a nice way to speed up the graph if you only want to see dependency relationships and build progress.

label_tar_visnetwork

Character vector, label argument to tar_visnetwork().

level_separation

Numeric of length 1, levelSeparation argument of visNetwork::visHierarchicalLayout(). Controls the distance between hierarchical levels. Consider changing the value if the aspect ratio of the graph is far from 1. If level_separation is NULL, the levelSeparation argument of visHierarchicalLayout() defaults to 150.

degree_from

Integer of length 1. When you click on a node, the graph highlights a neighborhood of that node. degree_from controls the number of edges the neighborhood extends upstream.

degree_to

Integer of length 1. When you click on a node, the graph highlights a neighborhood of that node. degree_to controls the number of edges the neighborhood extends downstream.

height

Character of length 1, height of the visNetwork widget and branches table.

display

Character of length 1, which display to show first.

displays

Character vector of choices for the display. Elements can be any of "graph", "summary", "branches", or "about".

Value

A Shiny module UI.
