Web10 okt. 2024 · First, change the vertex labeling to numbers as in your second graph. Also, use layout_components so that the components are separated from each other. library (igraph) set.seed (1234) LOC = layout_components (df_graph) plot (df_graph, layout=LOC, vertex.label=1:vcount (df_graph)) This is OK, but the arrows are a mess. Web這是一種方法，我最初為集合添加一個組標識符（我假設你在實際集合中有這個），然后在制作一個更長的類型數據集之后，我按這個id分組，標識符有最大的價值。然后，我在初始 df 和這組具有 largest_value word、summarize 和 rename 的鍵行之間使用內部連接。 pilates lyss
