R: Split up a network into a list of subgraphs

uncombine_network {tergm}

R Documentation

Split up a network into a list of subgraphs

Description

Given a network created by combine_networks(), uncombine_network() returns a list of networks, preserving attributes that can be preserved.

Usage

uncombine_network(
  nw,
  ignore.nattr = c("bipartite", "directed", "hyper", "loops", "mnext", "multiple", "n",
    ".subnetcache"),
  ignore.vattr = c(),
  ignore.eattr = c(),
  split.vattr = ".NetworkID",
  names.vattr = NULL
)

Arguments

`nw`	a `network::network` created by `combine_networks()`.
`ignore.nattr, ignore.vattr, ignore.eattr`	network, vertex, and edge attributes not to be processed as described below.
`split.vattr`	name of the vertex attribute on which to split.
`names.vattr`	optional name of the vertex attribute to use as network names in the output list.

Value

a list of network::networks containing subgraphs on split.vattr. In particular,

their basic properties (directedness and bipartednes) are the same as those of the input network;
vertex attributes are split;
edge attributes are assigned to their respective edges in the returned networks.

If split.vattr is a vector, only the first element is used and it's "popped".

Examples


data(samplk)

o1 <- combine_networks(list(samplk1, samplk2, samplk3))
image(as.matrix(o1))

ol <- uncombine_network(o1)
