[igraph] Bug report

[David Morton EPFL]

Hi there,

You may want to fix this little thing

for the next release of igraph in R.

    m = matrix(c(1,2,3,4),2,2)

    graph.adjacency(m,"upper")

would work fine but

   graph.adjacency(m,"upper",weighted=TRUE)

wouldn't see the self-loops.

The same with other options of graph.adjacency (e.g. "both")

Ciao.
