Query the geonames web API for geographic data

Description

www.geonames.org is a service where you can query for global geographic data such as administrative areas, populated places, weather data etc.

Details

The functions in this package are mostly thin wrappers to the API calls documented at the geonames web services overview http://www.geonames.org/export/ws-overview.html.

A set of example calls are supplied in a file with the package. Once you have set your geonames username with options(geonamesUsername="myusernamehere") you can run this with source(system.file("tests","testing.R",package="geonames"),echo=TRUE)
