evcent()
was renamed to eigen_centrality()
to create a more
consistent API.
evcent(
graph,
directed = FALSE,
scale = TRUE,
weights = NULL,
options = arpack_defaults()
)
Graph to be analyzed.
Logical scalar, whether to consider direction of the edges in directed graphs. It is ignored for undirected graphs.
A numerical vector or NULL
. This argument can be used
to give edge weights for calculating the weighted eigenvector centrality of
vertices. If this is NULL
and the graph has a weight
edge
attribute then that is used. If weights
is a numerical vector then it is
used, even if the graph has a weight
edge attribute. If this is
NA
, then no edge weights are used (even if the graph has a
weight
edge attribute). Note that if there are negative edge weights
and the direction of the edges is considered, then the eigenvector might be
complex. In this case only the real part is reported.
This function interprets weights as connection strength. Higher
weights spread the centrality better.
A named list, to override some ARPACK options. See
arpack()
for details.
