[R] about power.law.fit

Dear all, I'm using igraph for some analysis about the network I have. I have a question about the function "power.law.fit". I wonder if there is any test for checking whether the "power.law.fit" is good for the input, i.e., under which situation, could we use this function to get a reliable res

[R] how to get degree according to the name of the node?

Hi all, I have two networks for the same group of the users. I want to compare individual's degree in different networks. But how could I get the degrere of the nodes according to its name? When I use degree(g1), I could only get a vector of the degree of each node. But when I turn to g2, I don't

[R] question about SNA in R, thanks!

Dear colleagues, I'm trying to have a look at the Assortative and Disassortative ( http://en.wikipedia.org/wiki/Assortative_mixing) of the network I have. But it seems that the igraph hasn't mentioned that yet. I have to get the in/out degree of the vertices of each edge and calculate the Pearson

[R] about qqmath, thanks!

Dear collegues, Is there anyone who ever used qqmath(). Actually, I want to know the distribution of the dependent varible. It's a count number, so it should be poisson or negative binomial distribution. But how could I use R to get the ë and á? Or to demonstrate the distribution to be negative

[R] about centralization

Hi all, Is there anyone who ever used igraph to calculate the index of "centralization" ? I tried my best but can't find it in igraph. The brief introduction to "centralization" can be found here , and I think it's an important index for measuring the centrality on the aggregated level.(http://fa

Re: [R] Welcome to the "R-help" mailing list (Digest mode)

Hi friends, Is there anyone who happened to import data set in the "DL" format into R for further analysis? In the package of "network", there's only a method named "read.paj()". So now, I have to get the dl file from the original data set, and use UCINET to convert it to .net file. It's too comp
