caugi (version 1.0.0)

to_graphml: Export caugi Graph to GraphML Format

Description

Converts a caugi graph to the GraphML XML format as a string. GraphML is widely supported by graph analysis tools and libraries.

Usage

to_graphml(x)

Value

A caugi_graphml object containing the GraphML representation.

Arguments

x

A caugi object.

Details

The GraphML export includes:

• Node IDs and labels

• Edge types stored as a custom edge_type attribute

• Graph class stored as a graph-level attribute

Edge types are encoded using the caugi DSL operators (e.g., "-->", "<->"). This allows for perfect round-trip conversion back to caugi.

# Get GraphML string
graphml <- to_graphml(cg)
cat(graphml@content)

# Write to file
if (FALSE) {
write_graphml(cg, "graph.graphml")
