Plots Variograms for Simulated Data

This function plots variograms for simulated geostatistical data generated by the function grf.

Keywords
spatial, dplot
Usage
# S3 method for grf
plot(x, model.line = TRUE, plot.locations = FALSE, …)
Arguments
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.

Value

A plot with the empirical variogram(s) is produced on the output device. No values are returned.

par(mfrow=c(2,1))
sim1 <- grf(100, cov.pars=c(10, .25))
# generates simulated data
plot(sim1, plot.locations = TRUE)

# plots the locations and the sample true variogram model

# generates 10 simulated data
plot(sim1)
# plots sample variograms for all simulations with the true model
