%description
Provides functions for efficient computation of non-linear spatial
predictions with local change of support (Hofer, C. and Papritz, A. (2011)
"constrainedKriging: An R-package for customary, constrained and
covariance-matching constrained point or block kriging"
<doi:10.1016/j.cageo.2011.02.009>).  This package supplies functions for
two-dimensional spatial interpolation by constrained (Cressie, N. (1993)
"Aggregation in geostatistical problems"
<doi:10.1007/978-94-011-1739-5_3>), covariance-matching constrained
(Aldworth, J. and Cressie, N. (2003) "Prediction of nonlinear spatial
functionals" <doi:10.1016/S0378-3758(02)00321-X>) and universal (external
drift) Kriging for points or blocks of any shape from data with a
non-stationary mean function and an isotropic weakly stationary covariance
function.  The linear spatial interpolation methods, constrained and
covariance-matching constrained Kriging, provide approximately unbiased
prediction for non-linear target values under change of support.  This
package extends the range of tools for spatial predictions available in R
and provides an alternative to conditional simulation for non-linear
spatial prediction problems with local change of support.
