Kriging
Usage
krige(prdpnt, point.obj, v1, var.mod.object,maxdist=NULL)
Arguments
prdpnt
|
a point object, generated by point() , at which prediction is carried out
|
point.obj
|
a point object, generated by point() , containing 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.

Description
Carry out spatial prediction (or kriging).Value
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.References
