In UncerIn2: Implements Models of Uncertainty into the Interpolation Functions

Description

This package is the main result of diploma thesis. It can provide a basic (random) data, grids, 6 models of uncertainty, 3 automatic interpolations (idw, spline, kriging), variogram and basic data visualization. All together it could make a basic tools to solve the problem of uncertainty in this world.

Examples

# dataset meuse import
data(meuse)

# S4 class object Points input data definition
points = Points(x = meuse$x, y = meuse$y, z = meuse$elev)

# building uncertainty model (based on uncertaintyError function)
uncertaintyModel = uncertaintyError(points)

# generate grid for IDW interpolation
gridDef.spat = Grid.def(points, TRUE) # SpatialPixels

# IDW interpolation process
IDW = idwUncertain(uncertaintyModel, gridDef.spat)

# visualization of results
Plot(IDW)
