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.
