Details

A convenience wrapper to getSymbols(x,src='oanda').

The most useful aspect of getMetals is the ability to specify the Metals in terms of underlying 3 character symbol or by name (e.g. XAU (gold) , XAG (silver), XPD (palladium), or XPT (platinum)).

There are unique aspects of any continuously traded commodity, and it is recommended that the user visit https://www.oanda.com for details on specific pricing issues.

See getSymbols and getSymbls.oanda for more detail.

Value

Data will be assigned automatically to the environment specified (the parent environment by default). If auto.assign = FALSE, the data from a single metal request will simply be returned from the function call.

If auto.assign = TRUE is used (the default) a vector of downloaded symbol names will be returned.

See getSymbols and getSymbols.oanda for more detail.
