Examples

dblist <- list(dbname="test", dbuser="postgres", dbhost="localhost",
               dbport="5432", dbpwd="hallo")

## Working with OSM Ways
ways <- sfOSM(dblist, elem="ways")
r <- filterSF(ways, id=4383033, plot=T);
r <- filterSF(ways, nodes="5339632222,5343805366,5343805367,5343805368,5343805369,5339632232",
              plot=T, fixed=T);
r <- filterSF(ways, tf="primary", version = 11, plot=T);
r <- filterSF(ways, tf=c("footway", "path"), version = c(11,12), plot=T);
r <- filterSF(ways, id=184691002, plot=T);
r <- filterSF(ways, tf="surface\"=>\"asphalt", plot=T);
r <- filterSF(ways, tf=c("footway", "path"), plot=T, pal=c("blue","red"));
r <- filterSF(ways, tf=c("secondary", "residential","footway", "path"),
              plot=T, pal=rainbow(5));

## Working with OSM Nodes
nodes <- sfOSM(dblist, elem="nodes")
r <- filterSF(nodes, tf="highway", plot=T);
r <- filterSF(nodes, tf="crossing", version=11, plot=T);
r <- filterSF(nodes, version=9,  plot=T);
r <- filterSF(nodes, id=26936524,  plot=T);
