[R] polynomial question

Dear R People:

Suppose I have (x-1)*(x-2) and would like to produce x^2 - 3x + 2.

I have tried
> polynomial(c(1,1)*c(2,1))

2 + x

from the polynom library, but as you can see, that doesn't do it.

Is there a function to do this please? I'm sure that I've done this before, but I can't remember the correct way.

Thanks,
Erin
