head.intgrd

This function extends print.sp by including a display and summary of the
interval slot for the object.

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.
