[igraph] calculate vertices statistical features like degree eccentricity etc

[Csaba Ragany]

Dear All,

I want to calculate some statistical features on vertices like degree, eccentricity etc. I found lots of features on the internet but I some of them are not implemented in igraph or I did not find the appropriate function...

So can you tell me how to calculate the below statistical features in igraph or is it possible?
- neighborhood connectivity
- topological coefficient
- degree centrality
- stress centrality
- Katz centrality

Thank you!
