setDefaultsLKinfo: Method for including default information in the LKinfo...

In LatticeKrig: Multi-Resolution Kriging Based on Markov Random Fields

Description

This method is used to define the various parts of the LatticeKrig model by including specific components in the LKinfo object. The specific instance of the function that is used depends on the geometry that has been specified. Typically one would would not need to use this method for a new geometry.

Usage

setDefaultsLKinfo(object, ...)
## Default S3 method:
setDefaultsLKinfo(object, ...)
## S3 method for class 'LKRectangle'
setDefaultsLKinfo(object, ...)
## S3 method for class 'LKBox'
setDefaultsLKinfo(object, ...)
## S3 method for class 'LKRing'
setDefaultsLKinfo(object, ...)
## S3 method for class 'LKCylinder'
setDefaultsLKinfo(object, ...)
## S3 method for class 'LKInterval'
setDefaultsLKinfo(object, ...)
## S3 method for class 'LKSphere'
setDefaultsLKinfo(object,...)

Arguments

object	An object of class LKinfo.
...	Additional arguments to a specific method.

Details

This method is used to include some default settings or components in the LKinfo object and is called from LKrigSetup with the initial (or partial) LKinfo list that is formed from the information passed by the user to LKrigSetup.

In creating a new geometry this method is not required but can be used to include convenient default values and also some checks on the arguments passed to LKrigSetup. Often there are several arguments for a geometry that make sense to set to simplify the use or to avoid bad things ....

For the LKRing geometry the defaults values follow the logic:

• alpha set to 1.0 if not specified and nlevel is 1

• a.wght set to 4.01 if not specified.

• the fixed part of the model (fixedFunction) uses the function LKrigPeriodicFixedFunction which insures the first component is periodic.

• the transformation matrix, V has the default diag( c(1,1)). Also in this function if V[1,1] is not 1 then an error is given.

For the LKSphere geometry the defaults values follow the logic:

• alpha set to 1.0 if not specified and nlevel is 1

• a.wght set to 6.01 if not specified.

• the fixed part of the model (fixedFunction) just includes a constant ( m=1)

• Default distance function is great circle distance, with sphere radius of 1.0.
