Hi everyone, The following is mysterious to me. David Brillinger (famous statistician at Berkeley) has an equation in a paper that is essentially g(x,y) = f(x,y) - e(x)- e(y) These are continuous functions. I am not sure how to do this with the discrete equivalents in R. Please tell me how to do what he means in R. Thanks very much for any help! Bill
