[R] question about surf.gls(spatial package) with NA/NaN/inf values

Hi all,

I need to fit a trend surface to a 3D-dataset with the surf.gls() function
but my data contain missing values. There is just 2 NA in a total of 360
data points but I can't suppresse the variable associated with these NA
values to the analysis. The problem is surf.gls can't manage with Na/NaN/inf
values, so I wanted to know if a similar function in R can do it. I precise
that there's no replicate in the (preliminary test) data so I can't estimate
these values
them easily.

Thanks a lot for help
