[adegenet-forum] Change Colors in Colorplot()

[Romain Lehnebach Cirad]

Hello everybody,

As a part of a study about dispersion and domestication of a cultivated 
species, we used sPCA as complement of others analyses. More 
specifically, we used colorplot() function based on the scores of the 
third first global components.
In order to facilitate the reading of our future readers, we want to 
keep the same colour scheme we used in other analyses. This colour 
scheme depict geographical origins of our samples. Thus, we want to 
produce a colorplot with colours according to other analyses.
I had a precise look on the construction of colorplot function, but I 
can not find the way to modify the function in order to obtain the 
expected colours ...
One way, I guess, is to modify the scores on each axis to obtain the 
good RGB combination.
But, it seems, quite hard to find the good combination, since we used 3 
axis ...

Any advices, ideas or suggestions are welcome.

Best regards.
Romain.
