Hey everyone,

I know I've come across this somewhere, in either the blue or white
books or in one of the help docs but I can't put my hand on it.

What's the name of the statistical notation used in R?

responseVar ~ anExplantory:anotherExplantory + thridExplantory

Is this part of a coherent framework of notation that is as applicable
to models which are not generalized linear models as to glms?

Are there alternative systems of notation which are equally effective or
even more general that any of you could point me towards?

I'm working on spatial analysis, including spatial stats, and trying to
understand the consequence of notation on the ability to do analysis.

thanks for any pointers,

adrian

Yes (and it comes from linear models).  It is a (slightly) modified
version of Rogers-Wilkinson notation

@Article{Wilkinson.Rogers.73,
  author       = "G. N. Wilkinson and C. E. Rogers",
  title        = "Symbolic description of factorial models for analysis of
                  variance",
  journal      = "Applied Statistics",
  volume       = "22",
  pages        = "392--399",
  year         = "1973",
  comment      = "Reference from MASS",
}

also used by Genstat and GLIM.
