Dear Sir/Madam,How to use getSymbols() to get annual data? For example, I need the annual stock price of APPLE from the year 2000 to 2016. How to write the command? I only know how to get the daily data. It is: getSymbols("AAPL",from="2000-01-01",to="2016-12-31")
Presumably you'd need to loop over the years: get all the daily data in a year, calculate the overall High and Low, take the Open from the first date, the Close from the last one, and repeat.
