This is more of a statistics question than a question about help for R, so forgive me.

- First problem, I got this error message:

> z <- lda(C0GRP_NA ~ ., dpi30)

Warning message: variables are collinear in: lda.default(x, grouping, ...)

I guess this is not a good thing, however, I *did* get a result and it discriminated perfectly between my groups. Can anyone explain what this means? Does it invalidate my results?

Many thanks in advance for your help
