Arguments

References

  • Schlather, M. (2010) On some covariance models based on normal scale mixtures. Bernoulli, 16, 780-797.

Examples

Run this code
RFoptions(seed=0) ## *ANY* simulation will have the random seed 0; set
##                   RFoptions(seed=NA) to make them all random again


### Example 10 in Schlather (2010).
## The field below has more than 80 million points. So the simulation
## takes a while
y <- x <- seq(0, 10, len=256)
T <- c(0, 0.02, 1275)
col <- c(topo.colors(300)[1:100], cm.colors(300)[c((1:50) * 2,
         101:150)])

model <- RMcoxisham(mu=c(1, 1), D=matrix(nr=2, c(1, 0.5, 0.5, 1)),
                    RMwhittle(nu=1))
z <- RFsimulate(model, x, y, T=T, sp_lines=1500, every=10)
plot(z, MARGIN.slices=3, col=col)
plot(z, MARGIN.movie=3) # add 'file="ci.avi"' to get it stored
