[igraph] basic question on selecting a vertex

[Simone Gabbriellini]

Dear List,

sorry for this very basic question, but I am trying to select a vertex
based on the value of an attribute. I forgot the R syntax, and I got
lost trying to pick it up again...

I would like to create an edge between two nodes for which I only know
the value of the attribute, like:

add.edges(g, c( the-ID-of-vertex-with-name=="this",
the-ID-of-vertex-with-name=="that"))

can you please advice?

Best,
Simone
