Re: [igraph] saving hrg to disk

[Gábor Csárdi]

Hi, 

there is no API for this. But igraph_hrg_t is just 

typedef struct igraph_hrg_t {

  igraph_vector_t left, right, prob, edges, vertices;

} igraph_hrg_t;

so you could iterate over the vectors and save all of them in any format you like.

Hi Everyone,

I'm trying out igraph in C right now and am wondering if i there is a a function to save a hrg object. I'm fitting the hrg to my graph and would like to save the state afterwards, so i can reuse the hrg later. 

Here you can see some sample code to (hopefully) clarify what i'm trying to do:

//load graph

FILE *input;

igraph_t graph;

input=fopen("gn_no.pairs","r");

igraph_read_graph_edgelist(&graph, input,0,1);

//hrg

igraph_hrg_t hrg;

        igraph_hrg_init(&hrg,igraph_vcount(&graph));

        printf("number V: %d\n",igraph_vcount(&graph));

igraph_hrg_fit(&graph,&hrg,0,0);

//save hrg at this point to disk

igraph_hrg_destroy(&hrg);

        igraph_destroy(&graph);

Best regards, 

Bastian
