Visualizing distance between nodes according to weights - with R

I'm trying to draw a graph where the distance between vertices correspond to the edge weights* and I've founde that in graphviz there is a way to draw such graph. Is there a way to do this in R with the igraph package (specfically with graph.adkacency)? Thanks, Noam (as once have been asked: draw a graph where the distance between vertices corr

I'm wondering about any method that would calculate distance between vectors of different length. Solution The Euclidean distance formula finds the distance between any two points in Euclidean space. A point in Euclidean sp
