drake_graph_info {drake}

Prepare the workflow graph for visualization

Description

With the returned data frames, you can plot your own custom visNetwork graph.

Usage

drake_graph_info(
  ...,
  from = NULL,
  mode = c("out", "in", "all"),
  order = NULL,
  subset = NULL,
  build_times = "build",
  digits = 3,
  targets_only = FALSE,
  font_size = 20,
  from_scratch = FALSE,
  make_imports = TRUE,
  full_legend = FALSE,
  group = NULL,
  clusters = NULL,
  show_output_files = TRUE,
  hover = FALSE,
  on_select_col = NULL,
  config = NULL
)

Arguments

...

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

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.

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

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 Makes all targets outdated, but keeps information about build progress in previous make()s.

make_imports

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

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.

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.

hover

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

on_select_col

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

config

Deprecated.

Value

A list of three data frames: one for nodes, one for edges, and one for the legend nodes. The list also contains the default title of the graph.

# Inspect the raw graph.

# Use the data frames to plot your own custom visNetwork graph.
# For example, you can omit the legend nodes
# and change the direction of the graph.
