Build CALLS edges between function nodes

Cross-references each function node's calls_list against the set of known user-defined node identifiers. Each matched call produces one directed edge (from_node_id -> to_node_id).

Usage

build_call_edges(func_nodes)

Arguments

func_nodes

A list of node records as returned by extract_function_nodes().

Value

A data.frame with columns:

from

Character: node_id of the calling function.

to

Character: node_id of the called function.

weight

Numeric: edge weight (default 1).

Zero rows if no intra-project calls are found.

Details

The matching strategy is:

1. Exact match on bare function name (to_name).

2. Qualified match: if calls_list contains pkg::fn or pkg:::fn, the bare fn part is matched against known node names.

Only edges between nodes present in func_nodes are returned (intra-project edges). Calls to external packages are intentionally excluded here; use build_import_edges() for package-level dependencies.

Examples

if (FALSE) { # \dontrun{
proj  <- detect_rproject("/path/to/mypkg")
nodes <- extract_function_nodes(proj$r_files)
edges <- build_call_edges(nodes)
} # }
