"WebJun 24, 2024 · A graph, represented by G = (V, E), is a mathematical structure consisting of a set V of vertices and a set E of edges. The number of vertices and the number of edges in the graph are sometimes called the order and size of graph G (Kolaczyk et al., 2014). You may use V (graph) and E (graph) to check the vertices and edges; use vcount (graph ... " - Graph theory r
