WebbDetails. The diversity of a vertex is defined as the (scaled) Shannon entropy of the weights of its incident edges: D (i)=\frac {H (i)} {\log k_i} D(i) = logkiH (i) and k_i ki is the (total) degree of vertex i i, w_ {ij} wij is the weight of the edge (s) between vertices i i and j j . For vertices with degree less than two the function returns ...

Introduction to igraph
WebbAttributes are associated values belonging to a graph, vertices or edges. These can represent some property, like data about how the graph was constructed, the color of the vertices when the graph is plotted, or simply the weights of the edges in a weighted graph. WebbR语言igraph包diversity函数提供了这个函数的功能说明、用法、参数说明、示例 Webbgraph.disjoint.union creates a union of two or more disjoint graphs. Thus first the vertices in the second, third, etc. graphs are relabeled to have completely disjoint graphs. Then a simple union is created. This function can also be used via the %du% operator. graph.intersection creates the intersection of two or more graphs: only edges ... clarence and lois brooks fry
