Re: [igraph] experiences with combining igraph with one of the multicore/parallel processing packages from R

[Martin Tomko]

Thank you Gabor,
I am currently evaluating my options, being bound to Win and not having 
admin privileges on the Server... it is a pain.
Running multiple igraph functions at the same time is exactly what I want.

and I guess I have to rewrite some of my functions to fit lapply and 
similar functions, I have been using too many loops. But I am getting 
into troubles when I do something like lapply(graph,function), I guess 
because of coercing graphs into lists...

Anyway, I will report about how I go.
thanks
Martin
