Hi, I was wondering how could I resolve this issue : after using graph_simplify=simplify(graph,remove.multiple = TRUE,edge.attr.comb=list(Weight="mean")) and the type of the edge attribute weight change from n(numeric) to x(other) and when i execute sum(E(graph)$weight) , I got zero , how should I change the x type attribute to numeric one ?
thank you in advance, -- regards F..A
