Triad census per node

[Gábor Csárdi]

Also had a feature request I'd like to send your way. I know you have a triad.census() function, but it only returns summary stats for the entire graph. It would be really useful for social scientists to have a fast way to calculate and return the triad census positions of each node in a graph object. Perhaps it would be easy to modify the existing code to have igraph return this?

I have some R code to do this, but it's rather slow and doesn't scale well (I think because I am using so many R for loops). I have attached it in case it might be of use should you decide to port this functionality into igraph. I unfortunately do not know C well enough to do this myself. To see what it returns, run:

library(triads)
 n <- 20
 g <- barabasi.game(n, power = 1, m = NULL)
 triadcensus <- triadcensus(g)

Thanks for considering,
