plot.covariogram {geoRglm} | R Documentation |
Plots sample (empirical) covariogram computed using the
function covariog
.
## S3 method for class 'covariogram': plot(x, max.dist = max(x$u), ylim = "default", type = "b", envelope.obj = NULL, ...)
x |
an object of the class "covariogram" , typically an
output of the function covariog . |
max.dist |
maximum distance for the x-axis. The default is the maximum distance for which the sample covariogram was computed. |
ylim |
limits for the covariogram values in the y-axis. The default
is from the minimum to the maximum value in x$v . |
type |
type of line for the empirical covariogram. The default is
"b" (dots and lines). For further details see documentation
for lines . |
envelope.obj |
adds a covariogram envelope computed by
the function covariog.model.env . |
... |
other arguments to be passed to the function
plot . |
This function allows visualisation of the empirical covariogram.
Together with lines.covariomodel
it can be used
to compare theoretical covariogram models against the
empirical covariogram.
Produces a plot with the sample covariogram on the current graphics device. No values are returned.

covariog
for covariogram calculations, lines.covariomodel
for
adding lines to the current plot,
covariog.model.env
for computation of covariogram envelopes,
and plot
for generic plot function.
