Export caugi Graph to DOT Format

Converts a caugi graph to the Graphviz DOT format as a string. The DOT format can be used with Graphviz tools for visualization and analysis.

Usage

to_dot(x, graph_attrs = list(), node_attrs = list(), edge_attrs = list())

Arguments

x

A caugi object.

graph_attrs

Named list of graph attributes (e.g., list(rankdir = "LR")).

node_attrs

Named list of default node attributes.

edge_attrs

Named list of default edge attributes.

Value

A caugi_dot object containing the DOT representation.

Details

The function handles different edge types:

• Directed edges (-->) use -> in DOT

• Undirected edges (---) use -- in DOT (or -> with dir=none in digraphs)

• Bidirected edges (<->) use -> with [dir=both] attribute

• Partial edges (o->) use -> with [arrowtail=odot, dir=both] attribute

Examples

cg <- caugi(
  A %-->% B + C,
  B %-->% D,
  C %-->% D,
  class = "DAG"
)

# Get DOT string
dot <- to_dot(cg)
dot@content
#> [1] "digraph {\n\n  // Nodes\n  A;\n  B;\n  C;\n  D;\n\n  // Edges\n  A -> B;\n  A -> C;\n  B -> D;\n  C -> D;\n}"

# With custom attributes
dot <- to_dot(
  cg,
  graph_attrs = list(rankdir = "LR"),
  node_attrs = list(shape = "box")
)
