perf() and stable variables

[Florian Rohart]

In perf.spls and perf.splsda, the stable variables are obtained with a sort(summary(...)). This is a problem because it's only showing 100 levels of the factor. The use of table() should be preferred.

ok?

[Kim-Anh Le Cao]

I agree. Will make those changes when I get the time.
