Hi All, I'm working with igraph in R and I'm trying to create an edge attribute in my network based on nodes' similarity on a vertex attribute. I already have the vertex attribute read into the igraph object.
For example, "speakers" is an igraph object with vertex attribute "birthyear." I want to create an edge attribute "ageband5" with value 1 if two vertices in a dyad have birthyear within 5 years from one another. Alternatively, "birthyeardiff" could be an edge attribute that is the difference between the "birthyear" of each vertex in a dyad. How can this be done? Thank you, Richard
