[adegenet-forum] Adding phenotypic info to PCA or DAPC

[Stefano Montanari]

Dear adegenetters,

I would like to add a phenotypic trait to SNP data to use in either a PCA
or DAPC. Specifically, I have quantified colour in a specific region of the
body of fishes. The variable is a proportion. I have 2 species and their
hybrids, and would like to plot the clusters on a bidimensional area,
including the colour as one the components (either by colouring the
individuals, or showing it superimposed as a loading). Do you have any
suggestions as to how to go about doing this?

Cheers

Stef
