Re: [R] change individual label colours in a cluster plot?
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.

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.

I am doing some bibliometric analysis of interdisciplinarity using cluster analysis of co-authorship. I'd like to be able to specify the colour of individual authors in the labels to show a prior grouping by discipline (red for sociology authors, blue for economics authors, ..., that sort of thing). Is there any way of doing this sort of thing? I'm hoping for something like: h - hclust(authors.dist) h$labels - colorlabels(c(red, blue,..., green)) plot(h) __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. _ [[alternative HTML version deleted]] __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
