A mechgraph is an S3 list holding a node\ntable, an edge table, and provenance metadata. The package\nimplements builders that convert STRING and BioGRID interaction\ntables into mechgraph objects, combiners (mg_bind(),\nmg_combine()) that merge graphs while preserving duplicate\nevidence records, accessors (mg_nodes(), mg_edges(),\nmg_metadata()) and mutators (mg_add_*(), mg_drop_*()) for node\nand edge tables, filters by type, source, identifier, and\nscore, induced-subgraph construction, structural validation\n(mg_validate()), and quality-control summaries (mg_qc()).\nSzklarczyk et al.
