Dear igraph-help members,
I am post-doc working on analysis of social networks in groups of primates.
I write you because of the following reason:
On using the eigen_centrality function of the package igraph, I get the
following warning message:
"*eigen_centrality(GroomGiven,directed=TRUE)*
*Warning message:*
*In .Call("R_igraph_eigenvector_centrality", graph, directed, scale, :*
* At centrality.c:362 :Weighted directed graph in eigenvector centrality"*
The graph that I pass into the function is a network of grooming given. It
is a directed, weighted network (i.e. it is asymmetrical with weights of
the edges representing the number of times individual A groomed B).
I have searched in google and several other forums about this warning but
found nothing. So I was wondering if you could help me understand it. Is
this a warning because the matrix I pass into the function is directed?
because this is my actual intention (calculate the centrality scores of
each individual in this directed network), or is it something different
that may affect the calculation of the centrality scores?
Thanks for your time and reply.
Kind regards,
Dr. Ivan Puga-Gonzalez
