_O_v_e_r_v_i_e_w::

     The package makes functions available to download financial market
     data from the internet. Functions are availalbe for the  follwing
     web sites:

     1. Data from research.stlouisfed.org
      2. Data from www.oanda.com
      3. Data from chart.yahoo.com

     There are two kinds of functions available, the first kind is
     called  '*Series' which downloads a '"timeSeries"' object from a
     web site wher the star '*' is a placeholder for the web site
     (fred, oanda, and yahoo), and the second kind is called '*Import'
     which downloads an S4 object of class '"fWEBDATA"' wit a '@Data'
     slot which keeps the '"timeSeries"' object and further slots which
     keep additional download information.

     We recommend the first kind of functions for easy download of
     economic and financial time series, whereas we recommend to use
     the second kind of functions when additional information is
     required for example for the storage of the data in a data base
     management system.

     IMPORTANT NOTE: The download from the web site www.forecasts.org
     has been withdrawn since the time series are no longer updated.
     Note, all  the series offered by the "forecasts.org" web site are
     also available from the FRED St. Louis database.

     The following functions 

     1. fredSeries
      2. oandaSeries
      3. yahooSeries

     allow for an easy download of economic and financial time series
     data  as objects of class '"timeSeries"'.   

     Note, with version 280.73 major changes were made in the argument
     list of  the downloading functions. We apologize for any
     inconveniences caused by these changes. The reason was that now
     all functions have the same arguments which makes their usage much
     easier. For details we refer to  the help pages of the functions
     mentioned above.
