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
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.
