r中的igraph包:边缘标签重叠 [英] igraph package in r: edge labels are overlapping

问题描述

我正在使用R中的igraph软件包来可视化网络流.

I am working with the igraph package in R to visualise network flows.

library(igraph)

# Example Data:
b <- c("countryA", "countryB", "countryC", "countryA", "countryC", "countryA")
c <- c("countryB", "countryC", "countryA", "countryB", "countryA", "countryB")
d<- c(100, 200, 200, 300, 400, 200)
e <- c(5,12,10,24,25,12)
mydata <- data.frame(b,c,d,e)
colnames(mydata) <- c("exporteur", "partner", "tradeflow", "price")

# Plot in igraph
mydata.igraph <- graph.data.frame(mydata)
E(mydata.igraph)$label <- mydata[,3]
plot(mydata.igraph)

如您所见，我的边缘标签(箭头的标签)是重叠的.怎么解决呢?

As you can see, my edge labels (labels of the arrows) are overlapping. How to solve this?

提前谢谢！

推荐答案

这是执行此操作的代码.它使用边列表而不是igraph，但是它看起来很酷.

This is the code to do it. It uses the edgelist instead of the igraph, but it is a cooler looking graph.

    library(qgraph)
    qgraph(mydata,edge.labels=T)
