Hello, I'm sure this is a well-understood problem. I appreciate your patience.
I am attempting to use R as a visualization tool, pulling the data from my postgresql/postgis system. I have followed the examples from this page: http://www.bostongis.com/?content_name=postgis_tut01#20 All the software is working correctly, including RODBC so that I may issue queries to my database from within R. My question is, what is a good method for plotting the results of a sql query? For instance, "select * from towns" returns a column called the_geom, which is, I understand in Well Known Binary. If simply wish to plot the borders of the towns in R, I suppose I have to convert this to a spatial polygon. But honestly, I can't seem to figure this out. Nor can I find references on line that take WKB or WKT and plot this coordinates in R. So, I'm sure there is something fundamental that I am missing. I look forward to learning from your suggestions! -brian [EMAIL PROTECTED] ~~~ may all your sequences converge [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-geo
