weatherData is a library of functions that will fetch weather data (Temperature, Pressure, Humidity, Wind Speed etc.) from the Web for you as clean data frame.

If you want to perform weather Analysis, but don't wish to be bothered with scraping the data yourself, you can consider using weatherData.

How to Use this package


checkDataAvailabilityForDateRange("SFO", "2010-10-29", "2013-01-12")

The command above will see if weather data is available for the Airport supplied ("SFO") for the two end dates supplied: for the 20th Oct 2010 and for Jan 12th 2013 in this case.

This command is useful for a quick check, before invoking getDateRangeWeather


This is a data frame of Ambient temperature data, extracted from Weather Undergound. Each row has two entries (columns). The Timestamp (YYYY-MM-DD HH:MM:SS) and the TemperatureF (in degrees F)


This function will get the latest recorded Temperature for a give city or station. Any valid US Airport code or International 4-letter Airport Weather Code is valid. For example "EGLL" for London, UK. Note: This function uses the Sys.Date to learn today's date

getStationCode("Buffalo", state="WY")

This function will return a record containing matches to a given station name, and the 4 letter code can then be used in the arguments to other functions such as getWeatherForDate()
