Hi Jim, How are you? I saw your posting. I am trying to do clustering for co authorship.What I have is undirected graph .I want to have clusters for 393 nodes. I am attaching the file along with this mail.If you move to the section Cluster I am looking to do something like that.Is it something you are familiar with. Can you tell me how you did it in R. Nathan

Hi,
If you have a variable, that defines what you want to differentiate (sociology, economics etc.) then you can add color depending on the value of that variable. You will have to convert it to numeric if it is not. An example would be
plot( iris[ , 1 ], iris[ , 2], col = iris[ , 3 ] )
Thank you. I'm not sure that I can do that with an hclust object, though: perhaps something using the text function and the order data in the hclust object might work? Currently, I'm good getting results using a script to edit the postscript output, but I'm keen to find an R solution, if only to improve my understanding of R graphicss. Yours sincerely, -- Jim Ottaway
