%description
An interval-valued extension of ordinary and simple kriging. Optimization
of the function is based on a generalized interval distance. This creates
a non-differentiable cost function that requires a differentiable
approximation to the absolute value function. This differentiable
approximation is optimized using a Newton-Raphson algorithm with a penalty
function to impose the constraints. Analyses in the package are driven by
the 'intsp' and 'intgrd' classes, which are interval-valued extensions of
'SpatialPointsDataFrame' and 'SpatialPixelsDataFrame' respectively. The
package includes several wrappers to functions in the 'gstat' and 'sp'
packages.
