Hi,

I got some strange problem using igraph on R, when I try to read an graoh, which was some weeks ago written to file using igraph::write.graph(), can anybody help me?


graph <- read.graph("./graph.gml", format="gml")
Fehler in read.graph.gml(file, ...) :
  At rinterface.c:3988 : Cannot read GML file, File operation error


infos:
R: "R version 2.15.0 (2012-03-30)",
packageVersion("igraph"): ‘0.6.2’


Thanks
 stefan
