R：绘制igraph时选择性显示节点 [英] R: Selectively display nodes when plotting an igraph

问题描述

如何绘制igraph节点的选择？

我有一个现有图形，但它太复杂。我希望能够放大节点的一部分。

我可以删除边缘的一个子集，但我无法弄清楚关闭'隔离的节点。

当使用网络包时， displayisolates = FALSE 参数做到这一点;它不显示这些孤立的节点。

布局算法也应该忽略'关闭'边缘。

例如：

  g1 < -  graph（c（0,1，1,2，2,2， 3））
 g2 < -  delete.edges（g1，E（g1，c（0,1）））
 plot（g2）
  pre> 
 
 
在绘制g2时，我不想显示节点0。 $ b

我只想指出，在上面的葡萄酒回答中，从图片0.6开始，删除.isolates函数中的 -  1索引更正是不必要的。请参阅Tamas的评论：

How can I plot a selection of igraph nodes?

I have an existing graph, but it is too complex.  I want to be able to 'zoom in' on a subset of the nodes.

I am able to delete a subset of edges, but I can't figure out how to 'turn off' the isolated nodes.

When using the network package, the  displayisolates=FALSE parameter does this;  it does not display these isolated nodes.

The layout algorithm should also ignore the 'turned off' edges.

For example:
g1 <- graph( c( 0,1, 1,2, 2,2, 2,3 ) )
g2 <- delete.edges(g1, E(g1, c(0,1)))
plot(g2)
When plotting g2, I want to not display node 0.

Thanks

I understand that users should not submit new answers to comment on other answers, but my edit was rejected and I don't have a high enough reputation to leave comments.

I just wanted to point out that in Wine's answer above, the "- 1" index correction in the deletes.isolates function is not necessary from igraph 0.6 onwards. See also Tamas' comment here: 

Plot only Edges with a specific weight - igraph
