This function sets a range of the parameters for the intamap-package,
to be included in the object described in intamap-package
getIntamapParams(oldPar,newPar,...)A list of the parameters with class intamapParams to be included in the
object described in intamap-package
An existing set of parameters for the interpolation process,
of class IntamapParams or a list of parameters for modification
of the default parameters
A list of parameters for updating oldPar or for
modification of the default parameters.
Possible parameters with their defaults are given below
Individual parameters for updating oldPar or for
modification of the default parameters.
Possible parameters with their defaults are given below
doAnisotropy = FALSEDefining whether anisotropy should be calculated
removeBias = NADefining whether biases should be removed, and in case yes, which ones
(localBias and regionalBias implemented
addBias = NADefining which biases to be added in the postProcess function.
This has not yet been implemented.
biasRemovalMethod = "LM"character; specifies which methods to use to remove bias. See below.
doSegmentation = FALSEDefining if the predictions should be subject to segmentation. Segmentation has been implemented, but not the use of it.
testMeanlogical; for copula method only; whether or not the predictive means (if calculated) should be tested for being reasonable
nmax = 50for local kriging: the number of nearest observations that should be used for a kriging prediction or simulation, where nearest is defined in terms of the space of the spatial locations. By default, 50 observations are used.
maxdist = Inffor local kriging: Maximum distance to neighbouring locations to be used in kriging or simulations
ngrid = 100The number of grid points to be used if an Averaged Cumulative Distribution Function (ACDF) needs to be computed for unbiased kriging
nsim=100Number of simulations when needed
block = numeric(0)Block size; a vector with 1, 2 or 3 values containing the size
of a rectangular in x-, y- and z-dimension respectively
(0 if not set), or a data frame with 1, 2 or 3 columns,
containing the points that discretize the block in the
x-, y- and z-dimension to define irregular blocks relative to
(0,0) or (0,0,0) - see also the details section of predict.gstat.
By default, predictions or simulations refer to the support of the data values.
processType = "gaussian" If known - the distribution of the data. Defaults to gaussian, analytical solutions also exists in some cases for logNormal. This setting only affects a limited number of methods, e.g. the block prediciton
confProj = FALSEIf set, the program will attempt conform projections in preProcess,
calling the function conformProjections.
debug.level = 0Used in some functions for giving additional output. See individual functions for more information.
nclus = 1it is possible to use parallel processing for some interpolation methods
(currently only the copula method), nclus defines the number of processes to
spawn. This requires previous installation of the doParallel package
...Additional parameters that do not exist in the default parameter set,
this could be parameters necessary for new methods within or outside the
intamap-package
