Extract ego-centric subnetwork with preserved class attributes

Wrapper around igraph::make_ego_graph() that ensures output retains "metanet" and "igraph" class structure. Supports single or multiple center nodes.

c_net_ego(graph, nodes, order = 1, mode = "all")

Arguments

graph: An igraph object with potential "metanet" class
nodes: Center node(s) for subnetwork extraction (vertex IDs or names)
order: Integer specifying the order of neighbors to include
mode: Character scalar, either "in", "out" or "all" for directed networks

Value

metanet

Examples

library(igraph)
c_net_plot(co_net)

c_net_plot(c_net_ego(co_net, "s__Kribbella_catacumbae"))

nodes <- c("s__Kribbella_catacumbae", "s__Verrucosispora_andamanensis")
c_net_plot(c_net_ego(co_net, nodes))
