Examples

data(noise)
 if (require(sp)) {
   plot(malilla)
   points(obs, pch=19, col='red')

   ## geodata structure with transformed covariates
   covarnames=sapply(1:3, function(x) paste("d2TV", x, sep=""))
   obs1.df <- as.data.frame(cbind(Leq=obs$Leq,
                            1/(1+(as.data.frame(obs)[covarnames]/20)^2)))
   obs.gd <- as.geodata(cbind(coordinates(obs), obs1.df),
                        data.col="Leq",
                        covar.col=c('d2TV1','d2TV2','d2TV3'))
   plot(obs.gd)
 }
