Hi, once a Postgis layer X is retrieved, how can I juggle with subsets of X?
eg. I am working with bubble plots on a EU dataset but I want to do test it only using a 30x30Km in the nearby of Rome and I have no attribute data but the value I use for the bubbles. Should I use "subset"? Can I set a kinda of custom bbox? regards -r [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
