[igraph] graph.adjacency for directed, weighted graph

[Fletcher,Robert]

Dear list,

 

I am having a problem with creating an appropriate igraph object using the graph.adjacency function. My network is weighted and directed. When I use the following code:

 

Agraph<-graph.adjacency(A,mode="directed",weighted=TRUE, diag=FALSE)

 

The weights are not correct (this tends to  produce very small, non-zero values for E(Agraph)$weight). In this example, A is an integer matrix. This code worked on previous versions of igraph, but does not appear to be working in 0.6-3.  Any advice would be greatly appreciated.
