Strength of a vertex
The strength of a vertex is the sum of the weights of the edges adjacent on that node. The strength function gives us the strength of vertices in our graph. Let's look at a small code snippet to find the degree and strength of a graph:
> degree(simple.graph) alice bob charlie david eli 1 1 3 1 2 > E(simple.graph)$weight <- c(10,20,35,15,25,35)> strength(simple.graph) alice bob charlie david eli 10 20 70 35 25
The functions degree and strength in igraph package can be invoked to get degree and strength.
