To create a more end-user readable table captions for modeld, I would like
to get rid of the I(...) construct in formulae ("what's the hell does the
I(..) mean in the contrast table")Example: effect ~ I(sqrt(nitro))*treat + I(nitro^2) should giv effect ~ sqrt(nitro)*treat + nitro^2 In know, this is a dumb model, just my test case. As far I remember, finding matching parentheses is nasty in regexp, so I resorted to a loop and counting opening/closing. Is there a more elegant solution?
