Thank you for the reply!
I need to use it in the package for constructing the contrast matrices.
Really?
Renaming a variable like y2 <- y^2 will not be a solution for me...
With sufficient effort and diligence (and programming skill) I am
sure that this
technique could be made to work in your context.
Will try to look whether the function dummy.coef can be modified to work this
issue.
As I said before, the problem is really buried inside the
all.vars() function, whose workings are
buried in the R internals. This would not be at all easy (and
would probably be dangerous)
to modify.
cheers,
