Exercise

Set default arguments for a getSymbols source

You can also use setDefaults() on individual getSymbols() source methods. This exercise will teach you how to change the default value for the from argument to getSymbols.yahoo().

You can find the arguments for a specific method by using help() (e.g. help("getSymbols.yahoo") or by calling args() to print them to the console (e.g. args(getSymbols.yahoo)). Calling getDefaults() will show you the current default values (if there are any).

Remember, you are not supposed to call getSymbols.yahoo() directly!
