Re: [igraph] igraph problem with plotting - R version

[Gábor Csárdi]

Hi Simone, the problem is that your graph has a 'shape' vertex
attribute, and that is interpreted by 'plot', but its values are not
known shapes. I agree that the error message could be better....

Remove the attribute, or rename it, and then it will work fine.

Best,
G.
