Re: [igraph] igraph R read_graph

Hi,

Yes, that was the case. The problem was in the written name of the file. It is now solved.

Thank you so much

Hi,

Judging from the source code of the R interface, it seems like that the file simply doesn't exist; I get the same error message if I try something like read_graph("this_file_does_not_exist", "graphml").

Can it be the case that your file is called "Network.graphml" and not "network.graphml"? At least this is the case for the attachment...

Hi,

I want to read the attached graphml file in R using the command:

read_graph("network.graphml", "graphml")

But it shows the following error:

Error in read.graph.graphml(file, ...) :
  At rinterface.c:6077 : Cannot open GraphML file, File operation error

Do you know what the problem is and how I can solve it?

Regards,
