Re: [R] Clustering analysis with ordination plots
Please read the posting guide for future questions. I presume you mean using the vegan package? If so, then see this blog post of mine which shows how to do something similar: http://wp.me/pZRQ9-73 If you post more details and an example I will help further if the blog post is not sufficient for you to get the solution you want.

I have clustered an environmental matrix We do not know what that is. Where is the example data? See the posting guide. with 2 different methods, Which? Where is the reproducible code? See the posting guide. and I'd like to plot them in a PCA PCA is a method for reduction of dimensions. Frequently, if reduction works nicely, you can find clusters when plotting the first few PCs. But "plot them [clusters] in a PCA" is semantically invalid. and a db-RDA. What is a db-RDA? I mean, I want see these clusters in the plots like points of differents colours, together with the rest information of the plot, but I don't know how to do this. Tells us how you clustered the data and how you visualized it so far and we may be able to show you how to go ahead. I've checked a lot of bibliography and forums, and I haven't found the solution... it can't be so hard! Well, thanks in advance! :) But really, read the posting guide in advance of follow up questions: It helps to improve the way you ask questions and hence you will probably get more useful answers.

[R] Clustering analysis with ordination plots
Hello to all, I'm new to R so I have a lot of problems with it, but I'll only ask the main one. I have clustered an environmental matrix with 2 different methods, and I'd like to plot them in a PCA and a db-RDA. I mean, I want see these clusters in the plots like points of differents colours, together with the rest information of the plot, but I don't know how to do this. I've checked a lot of bibliography and forums, and I haven't found the solution... it can't be so hard! Well, thanks in advance! :) -- View this message in context: http://r.789695.n4.nabble.com/Clustering-analysis-with-ordination-plots-tp4598695.html Sent from the R help mailing list archive at Nabble.com. __ 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.
