Hi,
I have a problem with graph read.graph() in a Mac (but the same code R and
igraph version in Windows does work).
In a Mac I have:
read.graph("~/tmp/simple.graphml",format="graphml")
Error in read.graph.graphml(file, ...) :
At rinterface.c:4962 : Cannot open GraphML file, File operation error
Under Windows it reads it in OK.
I am running Mac MountainLion, R 2.15.1, igraph 0.6.2
Tested on a sample graphml file from
http://graphml.graphdrawing.org/primer/simple.graphml
and it seems to happen for any graphml (or gml) file that I try.
Looking back through the list it seems there was a problem in the past with
encoding so I converted to utf-8 but it does not help.
I am trying to avoid loading a debugger and hope that someone else has come
across this…
