How to convert igraph file in row/colums?

I would like to pass the information I have to a normal list of axes with nodes but I don't know how to do it. The raw data with "deput" would look like this. If someone knows how to convert this list into something easier to use I would appreciate it.I can visualise the graph with "plot" but to edit it I need to have more precise information.

library(igraph)
dput (net2$graph_pajek)
structure(list(30, FALSE, c(1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 
3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 5, 5, 5, 6, 7, 13, 13, 
14, 15, 16, 18, 20, 20, 21, 27, 27, 27, 27, 29, 2, 2, 2, 2, 2,

Are you looking for something like get.data.frame

> get.data.frame(net)
   from to     weight
1     A  B 0.63502922
2     B  C 0.79410173
3     C  D 0.90802625
4     D  E 0.09408188
5     E  F 0.16450634
6     F  G 0.75931882
7     G  H 0.30409658
8     H  I 0.23990324
9     I  J 0.84762277
10    A  J 0.88657718

data

Since I cannot reproduce the example in your post, I created a dummy example net like below

net <- make_ring(10) %>%
  set_vertex_attr(name = "name", value = LETTERS[1:vcount(.)]) %>%
  set_edge_attr(name = "weight", value = runif(ecount(.)))

To clarify a couple things:

  • The igraph file is not a plot per se, but a graph structure (as in, nodes and edges).
  • igraph has functions for plotting graphs, but there is no single and standard way of plotting a graph - instead, different algorithms can be used to determine visually-ideal ways of displaying them, and these algorithms oftentimes rely on random initializations.
  • The outputs from the plotting functions of igraph are only relevant in terms of R base plot drawing logic, AFAIK they don't use an intermediate format with coordinates handled in a user-comprehensible structure. You can nevertheless manage lots of aspects of how they are drawn - see ?igraph::igraph.plotting.
