Link prediction in social network with R
...in igraph.
So my questions are:
1) What do I need to do to obtain the scores for the links instead of the nodes (I presume it must be a data preparation step that I must be missing out)?
2) Which R package would be the best for running the various techniques - Jackard index, Adamic-Adar, common neightbours, PropFlow, etc
3) How to implement a supervised learning method such as random forest (I am guessing I need to obtain a feature list but again, how can I get the scores for the edges)?
Hope I've explain my questions well but do let me know if more clarification is need.
Thanks in advance...

shading in image()
...interp.surface(list(x=x,y=y,z=volcano),make.surface.grid(list(newx
,newy)));
dim(volcano2)<-c(length(newx),length(newy));
image(newx,newy,volcano2, col = terrain.colors(100))
As you see NANs are lareger in the interpolated image, I've modified the
interp.surface function to take the nearest neightbour when any of the 4
bounding points is NA but the result is still not perfect, thats why I'm
looking for a function that does Gouraud shading.
Thanks for all the help,
Angel
