I am working off an example from Deepayan Sarkar's Lattice:Multivariate Data Visualiization with R. I am trying to create Figure 5.6, essentially, but I would like to be able depict different metro areas. These of course have different lat/longs, so I need to make different graphs. BUT (and this has been the tricky part), I would like to produce graphics for each metropolitan

...e, and I don't really know how to interpret what is going on. The subsequent lines, I'm pretty sure, represent the empirical Ghat and the simulation envelope...but that first plot stumps me. You can see a pdf of the resulting plot if you download it from my website : www.bol.ucla.edu/~lschwei/sample.pdf WARNING: this is immediate download. THE CODE: ###### ghat.env <- function(n, s, r, win=owin(myOwin){ hold <- matrix(0, s, length(r)) for(i in 1:s){ hold[i,] <- Gest(runifpoint(n, win=myOwin), r=r)$raw } mn <- apply(hold, 2, mean) Up <- apply(hold, 2, max) Down <- a...
