Hi,

spca seems to work well on my AFLP data,

3 questions :

-  I need to scale (scale =TRUE) the data, and I do not understand the reason.
- Another problem  the function screeplot does not work on my spca object.?
- Is it possible to start spca from a  matrix of genetic distance between genotypes ?

If anyone can help ...
