Analysis of the structure of an ecological flow network.
Value
- A
- ns
A vector of structure based network statistics. These include n = number of nodes, L = number of edges, C = connectivity, LD = link density, ppr = pathway proliferation rate, lam1A = dominant eigenvalue, mlam1A = multiplicity of dominant eigenvalue, rho = damping ratio, R = distance of the dominant eigen value from the eigen spectra, d = difference between dominant eigen value and link density, no.scc = number of strongly connected components, no.scc.big = number of strongly connected components with more than one node, pscc = percent of nodes in strongly connected components.
