...icating that the step has been reduced below the minimum step size or an inifinity is generated in numericDeriv. I've tried to use a variety of starting values for a, b, k but get similar errors. Is there anything I can do to get the a fit or is there an alternative to the nls function? -- Suchandra Thapa <s-thapa-11 at alumni.uchicago.edu>

Thanks to Peter Dalgaard and Suchandra Thapa for answering my question! Before I settle on a particular option, I'd like to ask one more question if I may: Are there any practical advantages to compiling R to 64-bit vs 32-bit?

I'm trying to find a way to fit a polynomial of degree n in x and y to a set of x, y, and z data that I have and obtain the coefficients for the terms of the fitted polynomial. However, when I try to use the surf.ls function I'm getting odd results. > x <- seq(0, 10, length=50) > y <- x > f <- function (x, y) {x^2 + y} > library(spatial) > test <-

(Thanks for answers on my naif dual processor question!). I'm going to compile R-1.4.0 for linux (Suse 7.3) and hesitate at including the gnome interface. Do people that have tried the gnome interface recommend it? How is R started with this interface?
