Highlight a subset of the KEGG graph

Source: R/network_operations.R
highlight_kegg_graph.Rd

Highlight a subset of the graph based on KEGG IDs

Usage

highlight_kegg_graph(g, ids_to_highlight)

Arguments

g

An igraph object to visualize. Must have vertex attributes 'x' and 'y' for layout.

ids_to_highlight

Character vector of KEGG IDs to include in the highlighted subset.

Value

An igraph object with highlighted nodes and faded non-highlighted nodes and edges.

Details

This function highlights the nodes corresponding to the provided KEGG IDs and fades the rest of the graph. It modifies vertex attributes to achieve this effect.

Examples

pathway <- "mmu00230"
g <- create_kegg_graph(pathway)
#> adding rname 'https://rest.kegg.jp/get/mmu00230/kgml'
#> 
KEGG_to_include <- c("C00262", "C00385", "C00366", "C00294", "C00387",
                 "C01762", "C05512", "C00301", "C01185", "C00455",
                 "22436", "14544", "18950", "11486", "80285", "59027")
highlighted_subg <- highlight_kegg_graph(g, KEGG_to_include)
