我正试图获得有针对性的加权网络的中心度量.我一直在使用igraph和tnet包R.但是,我发现使用这两个软件包获得的结果存在一些差异,我对这些差异的原因有点困惑.见下文.

require(igraph)
require(tnet)
set.seed(1234)

m <- expand.grid(from = 1:4, to = 1:4)
m <- m[m$from != m$to, ]
m$weight <- sample(1:7, 12, replace = T)
igraph_g <- graph.data.frame(m)
tnet_g <- as.tnet(m)

closeness(igraph_g, mode = "in")

         2          3          4          1 
0.05882353 0.12500000 0.07692308 0.09090909 

closeness(igraph_g, mode = "out")

         2          3          4          1 
0.12500000 0.06250000 0.06666667 0.10000000 

closeness(igraph_g, mode = "total")

         2          3          4          1 
0.12500000 0.14285714 0.07692308 0.16666667 


closeness_w(tnet_g, directed = T, alpha = 1) …
