Convert a List of igraph Objects to Intralayer Edge Format — convert_to_intra

This function converts a multilayer network, represented as a list of igraph objects, into a standardized format suitable for Infomap and other multilayer network analyses.

Usage

convert_to_intra_format(igraph_list, use_names = FALSE)

Arguments

igraph_list: A list of igraph objects, each representing a network layer.
use_names: Logical; if TRUE, edges will use node names instead of numeric IDs (default: FALSE).

Value

A list with two data frames:

vertices: A data frame containing node_id and corresponding node names.
intra: A data frame containing intra-layer edges with columns: layer_id, node_id1, node_id2, weight.

Details

Each node is assigned a unique numeric ID, and edges across layers are recorded with layer-specific identifiers.

Examples

if (FALSE) { # \dontrun{
  multi_format <- convert_to_intra_format(list(layer1, layer2))
  print(multi_format$vertices)
  print(multi_format$intra)
} # }
