Find Bonacich alpha centrality scores of network positions

      alpha.centrality.Rdalpha.centrality() was renamed to alpha_centrality() to create a more
consistent API.
Usage
alpha.centrality(
  graph,
  nodes = V(graph),
  alpha = 1,
  loops = FALSE,
  exo = 1,
  weights = NULL,
  tol = 1e-07,
  sparse = TRUE
)Arguments
- graph
- The input graph, can be directed or undirected. In undirected graphs, edges are treated as if they were reciprocal directed ones. 
- nodes
- Vertex sequence, the vertices for which the alpha centrality values are returned. (For technical reasons they will be calculated for all vertices, anyway.) 
- alpha
- Parameter specifying the relative importance of endogenous versus exogenous factors in the determination of centrality. See details below. 
- loops
- Whether to eliminate loop edges from the graph before the calculation. 
- exo
- The exogenous factors, in most cases this is either a constant – the same factor for every node, or a vector giving the factor for every vertex. Note that too long vectors will be truncated and too short vectors will be replicated to match the number of vertices. 
- weights
- A character scalar that gives the name of the edge attribute to use in the adjacency matrix. If it is - NULL, then the ‘weight’ edge attribute of the graph is used, if there is one. Otherwise, or if it is- NA, then the calculation uses the standard adjacency matrix.
- tol
- Tolerance for near-singularities during matrix inversion, see - solve().
- sparse
- Logical scalar, whether to use sparse matrices for the calculation. The ‘Matrix’ package is required for sparse matrix support
