By the way, does anyone know an authoritative reference for the usual "model algebra", originating (I presume) with Nelder and Wilkinson and forming the basis for GLIM model specification and analysis?

I think the original paper is
@Article{flm:Wilkinson+Rogers:1973,
author = {G. N. Wilkinson and C. E Rogers},
title = {Symbolic Description of Factorial Models for
Analysis of Variance},
journal = {Applied Statistics},
year = 1973,
volume = 22,
pages = {392--399}
}
but I don't have a copy of the paper, so I don't know what's in there.
best,

Yes, I am sure this is right, thank you. It has no doubt developed a bit since then, possibly in a partly anarchistic way.

I put up a pdf copy from JSTOR at http://www.R-project.org/gR/papers/ Best, Z

Yes, certainly. For S, the white book is the key reference.
...although much of the "anarchy" is probably of a later date. AFAIR, the white book model formulas basically copies Genstat notation from 1977 for the lm/glm models (introducing the ~ operator and changing "." to ":" is about the extent of it, I think), which in turn more or less *is* Wilkinson/Rogers. Usage in other contexts and things like the "|" for conditioning in coplot or strata() terms came in later. Of course the department copy of the white book is nowhere to be found so I can't verify.
