[igraph] eigenvector cumulative distribution

[simone gabbriellini]

Dear List,

I see that it is always advisable to use cumulative log-log plot, like  
the one on the igraph screenshot page (http://igraph.sourceforge.net/screenshots2.html#8 
), when investigating for power law distributions...

I was wondering how to build a cumulative distribution of eigenvalues.

using for example:

eigen<-evcent(g, scale=TRUE, weights = E(g)$weights)
eigenvector<-eigen$vector
dd<-as.numeric(table(eigenvector))
dd<-dd/sum(dd)

I have a non cumulative distribution. How to make it cumulative?

best regards,
Simone
