Fehler in page.rank(g, options = myoptions) :
At arpack.c:1126 : ARPACK error, The Schur form computed by LAPACK routine dlahqr could not be reordered by LAPACK routine dtrsen.
I get this erro trying to manipulate the maximal iterations that the function should take for calculation.
Any help, please?

is it possible to apply another number of iterations the pagerank has to take instead of the standard value of 3000 (options$maxiter in page.rank). In the old pagerank (page.rank.old) you can give the niter parameter when calling the function. That way i would like to use the newer pagerank function page.rank. I want use the new page.rank because there you can calculate pagerank with preference vetctor or weightes vector… this is not possible with the old pagerank in igraph.
I need to calculate pagerank for dbpedia-entries with about 130 *10^6 edges and 18*10^6 vertices.
I hope someone can help this way.. best regards
