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").
