Hello! I have a spatio-temporal data set with 23 cities and 11 years of annual data. I have made it through krigeST without any problem. I use stplot and it works fine. It puts all of the plots on one page. My question: is there a way to have each of the stplots on separate pages, please?

Re: [R-sig-Geo] Fwd: spatio temporal variogram

Hi! When you make your shift from the first data set to the second, set it up such the the X1 - X4 are time series. For instance, if your data frame is called d1.df, d1.df$X1 - ts(d1.df$X1,start=1981,freq=12) (for monthly data) Hope this helps! Sincerely, Erin
