Ah, I want to set a specific coefficient value for each of the terms
rather than rely on training.  Thus given:

   y ~ x0 + x1 + x2 + a

I would like to set:

    a = 10
    b0 = 20
    b2 = 90,
    etc.

I'm trying out my own training model and I would like to use the machinery
of the lm for evaluation and reporting but I would like to fix the beta
coefficients and other trained values independently of least-squares
regression.
