[adegenet-forum] DAPC scatter plot and individual colour by population

[Jombart, Thibaut]

Hi

this is what I understood too. And my answer does exactly that - see the grp argument in ?scatter.dapc.
 
Cheers
Thibaut

Hi,

I think Nic just wants to color the DAPC scatter plot  not with the identified DAPC groups but with their respective population information.
So I guess he doesn't want to change the group discrimination method.

Did I get it right?

Best wishes,
Emrah

Hi there,

simple, just replace grp$grp with the grouping of individuals you want to use for the plot.

This said, be aware that the analysis is no longer optimal in terms of group discrimination.

Best

Subject: [adegenet-forum] DAPC scatter plot and individual colour by    population

Hi,

I built a DAPC scatter plot without using a priori grouping information (i.e. geographically distinct populations) using this simple command line: dapc1 <- dapc(data, grp$grp).

I obtained three distinct cluster but now I was wondering how I could  represent each individual with a colour corresponding to their sampling origin rather than to their inferred cluster.

I couldn't find this information on the manual and was hoping I could get some advice on that.

Thanks for your help!
Nic
