Convert KEGG pathway to igraph object
Usage
create_kegg_graph(pathway_id, kgml_file = NULL, verbose = FALSE)
Arguments
- pathway_id
Character, KEGG pathway ID (e.g., 'hsa04110') or
NULL if using kgml_file
- kgml_file
Path to a local KGML file (optional,
if pathway_id is provided)
- verbose
Logical indicating whether to print
verbose messages (default: FALSE)
Value
An igraph object representing the KEGG pathway graph
Examples
pathway <- "hsa04110" # Example pathway ID
graph <- create_kegg_graph(pathway_id = pathway, verbose = TRUE)
#> Downloading KGML file for pathway ID: hsa04110
#> Downloading KGML from: https://rest.kegg.jp/get/hsa04110/kgml
#> Cached: hsa04110
plot(graph) # Plot the graph using igraph's plotting functions
