Re: [igraph] a problem with simplify()

[Gábor Csárdi]

Hi Simone,

it should not be a problem, but it still is. simplify() is a single
function, and it does not keep the edge attributes, whatever its
arguments are. At least not in the 0.5 version, the 0.6 version is
already better.

A workaround is to use is.loop() and delete.edges(), this keeps all attributes.

Best,
Gabor
