Hello, I am looking into description of surf.ls(spatial) and see under value $beta - the coefficients. When I use polynomial of degree 2 to fit surface I expect to get 4 coefficients: z = a_1 x^2 + a_2 xy + a_3 y^2 + a_4 What do beta really stand for and why do I get $beta vector of length 6? Thakns, Mark

Hello, I am looking for a R routine to fit a function/surface to my data 3d data. I'd like to use the function in a model so something like splines is not applicable. The data are smooth and can provide a plot if helpful. Thanks, Mark

Hello, I'd like to remove color bar from "filled.contour" plot. Is it possible and how? I also want to overlay "contour" plot on filled.contour but due to scaling of the "filled.contour" to account for the color bar, aspect ratio for "contour" is different from "filled.contour". Can this problem be solved? Thanks, Mark
