we need rworldmap (>= 1.3.8) because in this version, the dependency on maptools was removed.
maptools creates a Warning: multiple methods tables found for ‘elide’ problem if used together with sp since they copied the elide method from maptools
also be more precise on a unit that was USD -> USD05 as discussed some days ago
