extractPar: Extracting parameters and their names from a spatio-temporal...

In gstat: Spatial and Spatio-Temporal Geostatistical Modelling, Prediction and Simulation

Description

All spatio-temporal variogram models have a different set of parameters. These functions extract the parameters and their names from the spatio-temporal variogram model. Note, this function is as well used to pass the parameters to the optim function. The arguments lower and upper passed to optim should follow the same structure.

Usage

extractPar(model)
extractParNames(model)

Arguments

model

a spatio-temporal variogram model from vgmST

Value

A named numeric vector of parameters or a vector of characters holding the parameters' names.

Examples

                        joint=vgm(60, "Exp",  84, 22),
