[igraph] R-implementations of games

[Arthur Kaiser]

Hallo,
do R-implementations of games exist?
I especially need a R-implementation of aging.prefatt.game.
Here is an example of a simple barabasi.game implementation:

my.ba.game<-function(n, directed){
        graph<-graph.empty(directed)
        graph<-add.vertices(graph, 1) #add first vertex


    for(i in 1:n){
        # snapshot
        # if(i==x) {write graph}

        # and the rest
        graph<-add.vertices(graph, 1) #add a vertex

        startvertices<-graph[4][[1]] #in degree

        maxj<-length(startvertices)

        j<-sample(1:maxj, 1)
        vj<-startvertices[j] #to

        if(maxj==0){graph<-add.edges(graph, c(i,0))
        }else{graph<-add.edges(graph, c(i, vj))}

    graph<-simplify(graph)
    }
return(graph)
}

Are you wondering why I ask for this? I need snapshots of the graph 
during the generation process. I also want to combine games e.g. ba with 
a d-dim latice or a randoom game without writing it in c and compile. 
Can someone help me please?

Thanks in advance.
