salsa: Find the SALSA as 'hub' or 'authority' score
In centiserve: Find Graph Centrality Indices

Description Usage Arguments Details Value Author(s) References Examples

The Stochastic Approach for Link-Structure Analysis (SALSA) is combination of HITS and PageRank which creates a neighborhood graph using authority and hub pages and links and create a bipartite graph of the authority and hub pages in the neighborhood graph.

1	salsa(graph, vids = V(graph), score = c("hub", "authority"))

`graph`	The input graph as igraph object
`vids`	Vertex sequence, the vertices for which the centrality values are returned. Default is all vertices.
`score`	Character constant, gives which score should be calculated and must be one of 'hub' or 'authority'. The default is 'hub'.

More detail at SALSA

A numeric vector contaning the centrality scores for the selected vertices.
