Dear Jeff,
I think you cannot escape discretizing your kriging surface as there is
no mathematical expression that captures the kriging surface. To use
optim you could make an objective function that was two inputs, x and y
location. The functions calls the fields package to estimate the krigi
Hi,
I am using the 'fields' package to conduct Kriging interpolation on my dataset.
I have managed to generate the 3-dimensional surface plot of the Krige-fitted
surface. There are several local minima points on the surface. My main interest
is to pinpoint the exact x-y coordinates of the low
