[R] 2.01

[Bang]

I recently installed the new base.

Code that I had been successfully using for a spatial model is now giving
the following message when it reads the "Y" variable in the command: 

y <- model.response(mf, "numeric")

The error it gives is: 

Error in model.response(mf, "numeric") : No direct or inherited method for
function "model.response" for this call

The code I've been using works in 1.9, not in the 2.  Is this an issue with
the program, and how can it be overcome?
