| Variogram {nlme} | R Documentation |
This function is generic; method functions can be written to handle
specific classes of objects. Classes which already have methods for
this function include default, gls and lme. See
the appropriate method documentation for a description of the
arguments.
Variogram(object, distance, ...)
object |
a numeric vector with the values to be used for calculating the semi-variogram, usually a residual vector from a fitted model. |
distance |
a numeric vector with the pairwise distances
corresponding to the elements of object. The order of the
elements in distance must correspond to the pairs
(1,2), (1,3), ..., (n-1,n), with n representing the
length of object, and must have length n(n-1)/2. |
... |
some methods for this generic function require additional arguments. |
will depend on the method function used; see the appropriate documentation.
