Converting between gexf and igraph classes

Source: R/igraph.R

Converts objects between gexf and igraph objects keeping attributes, edge weights and colors.

igraph.to.gexf(igraph.obj, ...)

gexf.to.igraph(gexf.obj)

Arguments

igraph.obj

An object of class igraph.
...

Further arguments passed to gexf().
gexf.obj

An object of class gexf.

Value

  • For igraph.to.gexf : gexf class object

  • For gexf.to.igraph : igraph class object

if (interactive()) {
  # Running demo
  demo(gexfigraph)
}
 
  fn <- system.file("gexf-graphs/lesmiserables.gexf", package = "rgexf")
  gexf1 <- read.gexf(fn)
  igraph1 <- gexf.to.igraph(gexf1)
  gexf2 <- igraph.to.gexf(igraph1)
  
if (interactive()) {
  # Now, let's do it with a layout! (although we can just use
  # the one that comes with lesmiserables :))
  pos <- igraph::layout_nicely(igraph1)
  plot(
    igraph.to.gexf(igraph1, nodesVizAtt = list(position=cbind(pos, 0))),
    edgeWidthFactor = .01)
