Usage
"variogram"(object, model = c("Sph", "Exp", "Gau", "Ste"), kappa = c(0.05, seq(0.2, 2, 0.1), 5, 10), fix.values = c(NA,NA,NA), verbose = FALSE, GLS.model = NA, start_vals = c(NA,NA,NA), miscFitOptions = list())
Arguments
object
Input data type of S4 object class UncertainPoints.
model
The list of variogrammodels that will be tested.
kappa
Smoothing parameter of the Matern model. Provide a list if you want to check more than one value.
fix.values
Can be used to fix a variogram parameter to a certain value. It consists of a list with a length of three. The items describe the fixed value for the nugget, range and sill respectively.
verbose
Logical, if TRUE the function will give extra feedback on the fitting process.
GLS.model
If a variogram model is passed on through this parameter a Generalized Least Squares sample variogram is calculated.
start_vals
Can be used to give the starting values for the variogram fitting. The items describe the fixed value for the nugget, range and sill respectively. They need to be given in that order. Setting the value to NA means that the value will be automatically chosen.
miscFitOptions
A list with named arguments that provide additional control over the fitting process. For example: list(merge.small.bins = TRUE). If the list is empty, autofitVariogram uses default values.
