Description

Adds n isolates to the adjacency matrix (or matrices) in dat.

Usage

add.isolates(dat, n)

Arguments

dat One or more adjacency matrices
n The number of isolates to add

Details

If dat contains more than one adjacency matrix, the n isolates are added to each member of dat.

Value

The updated graph stack.

Note

Isolate addition is particularly useful when computing structural distances between graphs of different orders; see the above reference for details.
