R help - Mar 2006 - products and polynomials in formulae

Hi
 
I can do this:
 
formula = as.factor(outcome) ~ .
 
in glm and other model building functions.   I think there is a way to
get the product of the determinants (that is d1 * d2, d1 * d3, etc) and
also another way to get all the polynomials (that is like poly(d1,2)
would produce for a single determinant).
 
Can anyone tell me how you write them?
