R1 R2 R3 A -1 0 -1 B 1 -1 0 C -1 -1 0 D 0 1 1 E 0 0 1
I would like to build a bipartite graph in igraph by following rules: - Edge directions should be determined by sign, i.e. when matrix entry is negative then direction is row-to-column, if it is positive then inverse direction. For example in first column, A and C connect to R1 but R1 connects to B.
- Graph should allow m<-1 and m>1 matrix entries for example -2, 3, etc. If this is the case, I wonder does igraph evaluate them as weight or attribute?
Best wishes.
