| plot.grf {geoR} | R Documentation |
This function plots variograms for simulated geostatistical data
generated by the function grf.
## S3 method for class 'grf': plot(x, model.line = TRUE, plot.locations = FALSE, ...)
x |
an object of the class grf, typically an output of the function
grf. |
model.line |
logical. If TRUE the true variogram model is added to the
plot with the sample variogram(s). |
plot.locations |
logical. If TRUE a plot with data locations is
also shown. |
... |
further arguments to be passed to the functions
variog and plot. |
A plot with the empirical variogram(s) is produced on the output device. No values are returned.

grf for simulation of Gaussian random fields,
plot.variogram for plotting empirical variogram,
variog for computation of empirical variograms and
plot for the generic plotting function.
