pip_graph: Build pipeline graph data

In pipeflow: Fast Interactive Data Analysis Pipelines

Build pipeline graph data

Description

Builds graph data (nodes and edges) describing the pipeline's step structure, suitable for visualisation with visNetwork::visNetwork().

Usage

pip_graph(x, include_upstream = FALSE)

pip_get_graph(x, include_upstream = FALSE)

Arguments

x	A pipeflow pip or view.
include_upstream	Logical. Only relevant for views. If TRUE, add all upstream dependencies of selected steps.

Details

Node shapes reflect execution mode:

• auto/plain: hexagon

• reduce: dot

• split: star

Value

A named list with two data.frames: nodes and edges.

Lifecycle

Deprecated

pip_get_graph() is a legacy alias for pip_graph(). It raises a deprecation warning and will be removed in a future release.

Examples

p <- pip_new()
pip_add(p, "load", \(x = 1) x, tags = "io")
pip_add(p, "clean", \(x = ~load) x + 1, tags = "io")
pip_add(p, "fit", \(x = ~clean) x * 2, tags = "model")

graph <- pip_graph(p)
graph$nodes # data.frame: id, label, shape, color
graph$edges # data.frame: from, to, arrows

# For a view, include_upstream = TRUE adds upstream deps to the graph
v <- pip_view(p, step = "fit")
pip_graph(v, include_upstream = TRUE)

if (require("visNetwork", quietly = TRUE)) {
  do.call(what = visNetwork::visNetwork, args = graph)
}
