[igraph] How to make several plots in igraph

[Marego Flua]

Hello,

I am a newer in igragh+R. I hope to know how to make the following plots
in igraph and R: 

1. Vertex strength as a function of its degree distribution.
2. Shortest path length distribution. 
3. Clustering coefficient C(k) as a function of the node degree k.
4. Cumulative betweenness distribution as a function of betweenness. 
5. The average nearest-neighbor degree as a function of the vertex degree. 

Thanks a lot for your help.
