Add Isolates to a Graph
Adds n isolates to the graph (or graphs) in dat.
add.isolates(dat, n, return.as.edgelist = FALSE)
dat |
one or more input graphs. |
n |
the number of isolates to add. |
return.as.edgelist |
logical; should the input graph be returned as an edgelist (rather than an adjacency matrix)? |
If dat contains more than one graph, the n isolates are added to each member of dat.
The updated graph(s).
Isolate addition is particularly useful when computing structural distances between graphs of different orders; see the above reference for details.
