correlogram(krig, nint, plotit = T, ...)
x
,
y
, and
z
x
and
y
coordinates of the correlogram, and
cnt
,
the number of pairs averaged per bin.
plotit = T
.
Divides range of data into
nint
bins, and computes the covariance for
pairs with separation in each bin, then divides by the variance.
Returns results for bins with 6 or more pairs.
