[igraph] how to pick a node with a probability proportional to its degree

[Simone Gabbriellini]

Dear List,

I am trying to pick up a vertex with a probability proportional to its
degree. I know that I can do:

degs <- degree(g)
sample(unique(degs), 1, replace=TRUE, prob = unique(degs))

to pick a degree with a probability proportional to its value, but how
then to retrieve the corresponding vertex (or one of the ones with
that degree value)?

Best,
Simone
