为网络图中的顶点分配一个(数字实数)值 [英] assign a (numeric real) value to vertex in network graph

问题描述

我想为网络图中的每个节点分配或关联R中的某个实际值(例如某个分数). 需要在迭代中进行更新. 最后根据其最新值(得分)绘制具有顶点大小的网络图.

I wanted to assign or associate each node in the network plot with some real value (say some score) in R. Which need to be updated in iterations. Finally to plot the network graph with size of vertex according to its latest value (score).

可以用于此目的的顶点的哪个属性?如何使用? 如果在igraph中不可能，在R中还有其他方法可以实现此目的吗?

Which property of a vertex I can use for this purpose and how? If it's not possible in igraph, is there any other way to achieve this purpose in R?

我是R的新手.任何人都可以帮助我解决这个问题.

I'm new to R. Anybody please help me to sort out this problem.

推荐答案

我创建我的差距

graph2 <- read.table(text = '1 2 
1 3 
2 5 
3 4 
3 5 
4 5 
5 6 ')                    
par(mfrow =c(1,2)) 
graph2 <- graph.data.frame(graph2, 
           vertices = data.frame(symbols = 1:6,label   = 1:6),directed=FALSE)
plot(graph2,main='simple graph')

我更改了weight属性，在这里您可以进行适当的压缩过程

I change the weight property , here you can pput yor proper compting process

E(graph2)$weight <- seq(ecount(graph2))
graph.strength(graph2)

我修改属性宽度，以可视化权重效果

I modify property width, to visualize the weight effect

E(graph2)$width <-E(graph2)$weight                     
plot(graph2,main='weighted graph')
