[R] (geostats) package in R to assess local nonstationarity?

[Paulo Justiniano Ribeiro Jr]

Hi Lawrence
 
The function "plot.geodata" in (geoR) plots data against coordinates.
Actually you don't need any package specific function to plot data
against coordinates or any other covariate. An example is:
# simulating data
ap <- grf(121, cov.pars=c(1, .25), grid="reg")
# plotting
plot.geodata(ap)
#
 
The pocket plots will be limited to data on a grid and I'm not sure they
are very useful. However this will be relatively easy to implement and
I'll add to the geoR ToDo list, please watch for the package updates.
 
Cheers
P.J.
