Hello,
Does anyone know how to calculate a simple moving average of 21 periods based on the close price from a stock data frame and add the SMA-21 to the data frame.

I don't know what SMA-21 is but for moving averages I would use the slider package.

Sorry, The SMA-21 is the simple moving average for the last 21 periods based on the stock close price from the TTR package using the get_symbols method.
