   AArrgguummeennttss::

     prdpnt: a point object, generated by `point()', at which
             prediction is carried out

   point.obj: a point object, generated by `point()', contain
             ing the sample points and data

         v1: the variable, contained in `point.obj', for which
             prediction will be carried out

    maxdist: an optional maximum distance. If entered, then
             only sample points (i.e, in point.obj) within
             maxdist of each prediction point will be used to
             do the prediction at that point. If not entered,
             then all n sample points will be used to make the
             prediction at each point.

        Carry out spatial prediction (or kriging).

   VVaalluuee::

        A point object which is a copy of the prdpnt object
        with two new variables, `zhat' and `sigma2hat', which
        are, repspectively, the predicted value and the kriging
        variance.
