My guess is because it's calculating matrix eigenvectors, there's an upper limit for graph size?Theoretically there isn't any upper limit, but the eigenvector calculations may fail to converge if your network is large. You have to explicitly instruct the ARPACK solver to allow more iterations using the options argument of leading.eigenvector.community -- I'm not sure about the details, however, since I don't use the R interface. See the documentation for more details. I guess you'll have to modify the variable called igraph.arpack.default (more precisely its element called "maxiter").
