Joining lists of networks, graphs, and matrices

These functions offer tools for joining lists of manynet-consistent objects (matrices, igraph, tidygraph, or network objects) into a single object.

• from_subgraphs() modifies a list of subgraphs into a single tidygraph.

• from_egos() modifies a list of ego networks into a whole tidygraph

• from_waves() modifies a list of network waves into a longitudinal tidygraph.

• from_slices() modifies a list of time slices of a network into a dynamic tidygraph.

• from_ties() modifies a list of different ties into a multiplex tidygraph

from_subgraphs(netlist)

from_egos(netlist)

from_waves(netlist)

from_slices(netlist, remove.duplicates = FALSE)

from_ties(netlist, netnames)

Arguments

netlist

A list of network, igraph, tidygraph, matrix, or edgelist objects.

remove.duplicates

Should duplicates be removed? By default FALSE. If TRUE, duplicated edges are removed.

netnames

A character vector of names for the different network objects, if not already named within the list.

Value

A tidygraph object combining the list of network data.
