pre-processing of the data for the intamap-package package.
# S3 method for default
preProcess(object, ...)
# S3 method for idw
preProcess(object, ...)see intamap-package; list that should at
least contain (i) an element called observations of class
SpatialPointsDataFrame. The measured values should be named
value, and (ii) an element params of class list, by calling the
function getIntamapParams. (iii) Usually, the object will also
contain an element called predictionLocations,
of a class extending Spatial.
Additional parameters
The input object is returned, after its components have been pre-processed.
The function preProcess includes code for preprocessing an object before interpolation.
The function can easily be replaced by more specific methods relevant for a
certain data set. Functions can be called from preProcess according to the settings in parameters
in the object, set by the function getIntamapParams.
