I could see that a STFDF object was created, but I still have some concern with regard to the "id" which need to be attached to the data.frame . With regards to my example, I tried as well with reverse-order IDs: > ds <- cbind(ds, time=sort(rep(dts,10)), id=nrow(ds):1) ...or with duplicated IDs like: > ds <- cbind(ds, time=sort(rep(dts,10)), id=rep(1:10,2)) and the final stMeuse object still seemed the same by looking at stplot(stMeuse). I guess they are not bound to the locations of the spatial object (points in `meuse` in this case). > (also note that with the CRAN version of spacetime, you'd need to load package zoo first in order to run your script) > Got it, thanks ;) Piero [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
