| sparsity {BDgraph} | R Documentation |
Compute the sparsity of a graph/network or an object of calss "graph" from function graph.sim or an object of calss "sim" from function bdgraph.sim.
sparsity( adj )
adj |
adjacency matrix corresponding to a graph structure in which a_{ij}=1 if there is a link between notes i and j, otherwise a_{ij}=0.
It can be an object with |
value corresponding to the graph sparsity which is the proportion of the non-links (non-zero elements) in adj.
