It is good practice to visualize the dependency graph before running the targets.

Usage

vis_drake_graph(
  ...,
  file = character(0),
  selfcontained = FALSE,
  build_times = "build",
  digits = 3,
  targets_only = FALSE,
  font_size = 20,
  layout = NULL,
  main = NULL,
  direction = NULL,
  hover = FALSE,
  navigationButtons = TRUE,
  from = NULL,
  mode = c("out", "in", "all"),
  order = NULL,
  subset = NULL,
  ncol_legend = 1,
  full_legend = FALSE,
  make_imports = TRUE,
  from_scratch = FALSE,
  group = NULL,
  clusters = NULL,
  show_output_files = TRUE,
  collapse = TRUE,
  on_select_col = NULL,
  on_select = NULL,
  level_separation = NULL,
  config = NULL
)

Arguments

...

Arguments to make(), such as plan and targets.

file

Name of a file to save the graph. If NULL or character(0), no file is saved and the graph is rendered and displayed within R. If the file ends in a .png, .jpg, .jpeg, or .pdf extension, then a static image will be saved. In this case, the webshot package and PhantomJS are required: install.packages("webshot"); webshot::install_phantomjs(). If the file does not end in a .png, .jpg, .jpeg, or .pdf extension, an HTML file will be saved, and you can open the interactive graph using a web browser.

selfcontained

Logical, whether to save the file as a self-contained HTML file (with external resources base64 encoded) or a file with external resources placed in an adjacent directory. If TRUE, pandoc is required. The selfcontained argument only applies to HTML files. In other words, if file is a PNG, PDF, or JPEG file, for instance, the point is moot.

build_times

Character string or logical. If character, the choices are 1. "build": runtime of the command plus the time it take to store the target or import. 2. "command": just the runtime of the command. 3. "none": no build times. If logical, build_times selects whether to show the times from `build_times(..., type = "build")“ or use no build times at all. See build_times() for details.

digits

Number of digits for rounding the build times

targets_only

Logical, whether to skip the imports and only include the targets in the workflow plan.

font_size

Numeric, font size of the node labels in the graph

layout

Deprecated.

main

Character string, title of the graph.

direction

Deprecated.

hover

Logical, whether to show text (file contents, commands, etc.) when you hover your cursor over a node.

navigationButtons

Logical, whether to add navigation buttons with visNetwork::visInteraction(navigationButtons = TRUE)

from

Optional collection of target/import names. If from is nonempty, the graph will restrict itself to a neighborhood of from. Control the neighborhood with mode and order.

mode

Which direction to branch out in the graph to create a neighborhood around from. Use "in" to go upstream, "out" to go downstream, and "all" to go both ways and disregard edge direction altogether.

order

How far to branch out to create a neighborhood around from. Defaults to as far as possible. If a target is in the neighborhood, then so are all of its custom file_out() files if show_output_files is TRUE. That means the actual graph order may be slightly greater than you might expect, but this ensures consistency between show_output_files = TRUE and show_output_files = FALSE.

subset

Optional character vector. Subset of targets/imports to display in the graph. Applied after from, mode, and order. Be advised: edges are only kept for adjacent nodes in subset. If you do not select all the intermediate nodes, edges will drop from the graph.

ncol_legend

Number of columns in the legend nodes. To remove the legend entirely, set ncol_legend to NULL or 0.

full_legend

Logical. If TRUE, all the node types are printed in the legend. If FALSE, only the node types used are printed in the legend.

make_imports

Logical, whether to make the imports first. Set to FALSE to increase speed and risk using obsolete information.

from_scratch

Logical, whether to assume all the targets will be made from scratch on the next make(). Makes all targets outdated, but keeps information about build progress in previous make()s.

group

Optional character scalar, name of the column used to group nodes into columns. All the columns names of your original drake plan are choices. The other choices (such as "status") are column names in the nodes . To group nodes into clusters in the graph, you must also supply the clusters argument.

clusters

Optional character vector of values to cluster on. These values must be elements of the column of the nodes data frame that you specify in the group argument to drake_graph_info().

show_output_files

Logical, whether to include file_out() files in the graph.

collapse

Logical, whether to allow nodes to collapse if you double click on them. Analogous to visNetwork::visOptions(collapse = TRUE).

on_select_col

Optional string corresponding to the column name in the plan that should provide data for the on_select event.

on_select

defines node selection event handling. Either a string of valid JavaScript that may be passed to visNetwork::visEvents(), or one of the following: TRUE, NULL/FALSE. If TRUE , enables the default behavior of opening the link specified by the on_select_col given to drake_graph_info(). NULL/FALSE disables the behavior.

level_separation

Numeric, levelSeparation argument to visNetwork::visHierarchicalLayout(). Controls the distance between hierarchical levels. Consider setting if the aspect ratio of the graph is far from 1. Defaults to 150 through visNetwork.

config

Deprecated.

Value

A visNetwork graph.
