Senthil,
sending a 12Mb file to the list is not a good idea.
I've run the code in my previous email without any problem, so you need
to be a bit more specific about what went wron

Senthil,
you can try the 'igraph' package. Export your two-column Excel file
as a .csv, use 'read.csv' to read that into R, then 'graph.data.frame'
to create an igraph graph from it. Final

It would seem that you can output the initial file from EXCEL, read it
into R with 'read.csv' and then use 'factor' to convert the characters
for City1 and City2 to the numbers that you want to use. Have you

Hello,
I am calculating 'Betweenness' of a large network using R. Currently, I have
the node-node information (City1-City2) in an excel file, present in two
columns where column A has City1 and column B has City2 that city1 is connected
to. These are the steps that I go through to calculate bet
