r - igraph：边没有被剪裁到无向图中的顶点

Question

当我更改vertex.sizeinigraph时，边缘不会被剪裁到顶点，它们会在顶点旁边结束几个点/像素。例子：

library(igraph)
set.seed(13)
g <- barabasi.game(500, directed = F)
plot(g, vertex.size = 2, edge.curved = T, vertex.label = NA, edge.arrow.mode = "-",
layout = layout.fruchterman.reingold)

似乎它不适用于有向图，因为箭头绘制在边缘的末端。

有没有办法解决这个问题？

Answer 1

我添加了edge.arrow.size它似乎可以解决它。

library(igraph)
set.seed(13)
g <- barabasi.game(500, directed = F)
plot(g, vertex.size = 2, edge.curved = T, vertex.label = NA, edge.arrow.mode = "-",   
edge.arrow.size=0.01,layout = layout.fruchterman.reingold)
