Download Federal Reserve Economic Data - FRED(R)

Description

R access to over 11,000 data series accessible via the St. Louis Federal Reserve Bank's FRED system.

Downloads Symbols to specified env from ‘research.stlouisfed.org’. This method is not to be called directly, instead a call to getSymbols(Symbols,src='FRED') will in turn call this method. It is documented for the sole purpose of highlighting the arguments accepted, and to serve as a guide to creating additional getSymbols ‘methods’.

Usage

getSymbols.FRED(Symbols,
                env,
                return.class = "xts",
                ...)

Arguments

Details

Meant to be called internally by getSymbols (see also).

One of many methods for loading data for use with quantmod. Essentially a simple wrapper to the underlying FRED data download site.

Naming conventions must follow those as seen on the Federal Reserve Bank of St Louis's website for FRED. A lookup facility will hopefully be incorporated into quantmod in the near future.

Value

A call to getSymbols.FRED will load into the specified environment one object for each Symbol specified, with class defined by return.class. Presently this may be ts, its, zoo, xts, or timeSeries.
