The problem is that using graph.neighborhood I get an output like this:
[[65]]IGRAPH DN 6 15 + attr: name (v/c), value (e/n)[[66]]IGRAPH DN 3 2 + attr: name (v/c), value (e/n)
where egos in my list are identified by a number in squared brackets. Since I need to work on a time series, I need to keep trace of the name of the egos, so that to build an egonetwork density time series for each of my nodes across 10 years.
As for "graph.density" it calculates density as ratio between number of ties and all the possible ties in the (ego)network, while I need to calculate it as number of ties over number of pairs. I was wondering if there's a direct function to perform it in place of "graph.density".
What if I create a list of networks, including all my 10 years, and than use "lapply" for "graph.neighborhood" and than for "graph.density"?
