Just make this clear. The example (repeated below) on the
stackoverflow page does _not_ convert the graph into an adjacency
matrix. The indexing only makes the graph look as if it was an
adjacency matrix. But there is no conversion at all.
ps. I would appreciate if you didn't cross-post your questions
everywhere (R-help, igraph-help and stackoverflow, maybe other places
as well). Please only post it on the platform you prefer first and
then, if you don't get a good answer, try elsewhere. Thanks!
g <- graph.ring(10)
#  1
E(g)$weight <- runif(ecount(g))
#  0.8115639
