[igraph] How to get neighborhood info using igraph in R

[Amit Kumar]

Hello,

I am using igraph in R to generate networks. I used erdos.renyi.game(100, 2/100) to generate a random graph.
Now, I need neighbourhood info from this graph as output (*.nei or *.txt) which should look like as follows:-

Node          No of neighbours          List of neighbours
1                       2                              21   27
2                       5                              11   20  23  9  8
-                        -                               --
-                        -                               --
-                        -                               --
-                        -                               --
100                   4                              89  78  77  34

I am newbie. Please be kind and help.

regards
Amit
