Variogram(object, distance, sig2, length.out, FUN)
corSpatial
,
representing spatial correlation structure.
object
, specifying the semi-variogram
model.
NULL
, in which case a sequence of length

variog
and
dist
representing,
respectively, the semi-variogram values and the corresponding
distances. The returned value inherits from class
