Dear Sir/ Madam,
I was wondering if someone could help me. I am trying to calculate
closeness centrality in R with a toy example:
ida,idb
1,2
1,5
2,4
3,2
6,1
2,6
7,2
d<- read.table("D:/data test/snatest.txt", header=F,
sep=",")
attach(d)
d
e<-network(d,directed=F,bipartite=7)
plot(e)
d<-as.matrix(d,colnames=F)
l<-graph.edgelist(d)
summary(l)
g <- graph(d,n=7)
summary(g)
closeness(g)
The problem is whenever I look at the summary for l it says I have 8
vertices even though there should be only 7? Is it my code or am I using
the wrong function.
Kind Regards,
Lorcan Treanor
