In rixpress: Build Reproducible Analytical Pipelines with 'Nix'

Create a Directed Acyclic Graph (DAG) Representing the Pipeline Using {ggplot2}

Description

Uses {ggdag} to generate the plot. {ggdag} is a soft dependency of {rixpress} so you need to install it to use this function. When derivations are organized into pipelines using rxp_pipeline(), nodes use a dual-encoding approach: the interior fill shows the derivation type (R, Python, etc.) while a thick border shows the pipeline group colour.

Usage

rxp_ggdag(
  nodes_and_edges = get_nodes_edges(),
  color_by = c("pipeline", "type"),
  colour_by = NULL
)

Arguments

nodes_and_edges	List, output of get_nodes_edges().
color_by	Character, either "pipeline" (default) or "type". When "pipeline", nodes show type as fill colour and pipeline as border. When "type", nodes are coloured entirely by derivation type (rxp_r, rxp_py, etc.).
colour_by	Character, alias for color_by.

Value

A {ggplot2} object.

Examples

## Not run: 
  rxp_ggdag()  # Dual encoding: fill = type, border = pipeline
  rxp_ggdag(colour_by = "type")  # Color entirely by derivation type

## End(Not run)
