get_alpha_centrality {DiagrammeR} | R Documentation |
Get the alpha centrality values for all nodes in the graph.
get_alpha_centrality(graph, alpha = 1, exo = 1, weights_attr = NULL, tol = 1e-07)
graph |
a graph object of class
|
alpha |
the parameter that specifies the relative importance of endogenous versus exogenous factors in the determination of centrality. |
exo |
the exogenous factors, in most cases this is either a constant (which applies the same factor to every node), or a vector giving the factor for every node. |
weights_attr |
an optional name of the edge
attribute to use in the adjacency matrix. If
|
tol |
the tolerance for near-singularities
during matrix inversion. Default value is set to
|
a data frame with alpha centrality scores for each of the nodes.
