Converting between gexf and igraph classes

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

Usage

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

Details

If the position argument is not NULL, the new gexf object will include the position viz-attribute.

Examples


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)
