Hi Stephen,

it seems that data.frame() drops the names. So put the labels explicitly in the data frame, either as row names:

row.names(c_1996) <- V(network)$name

Or, if that does not work, as a separate column:

c_1996<-data.frame(V(network)$name, c_1996)

I don't have stata, so I cannot try this...

Hi all,

I'm trying to export an object consisting of centrality measures I calculated to a Stata file. Specifically, my nodes are countries and I want the centrality measure associated with the particular country in the object so that I can export it to Stata with one column being country ids and the other column being the centrality measure for that particular country.

 However, for some reason when I calculate the centrality measure the labels do not appear to be attached, so when it is exported to Stata all that I get is one column of centrality measures unattached to any country ids. Below is my code; I'm a newbie to both R and igraph so apologies if this is a very simple question.



network<-read.graph("TradeTransitions_pajek_1996.net", format = "pajek")
c_1996<-closeness(network, mode="in")
write.dta(c_1996, "d:/Users/scranney/Desktop/TradeTransitions/c_1996.dta")
