Question

Use the install.packages function to install the BatchGetSymbols package on your computer. After installation, use function BatchGetSymbols to download price data for the IBM stock in the last 15 days. Tips: 1) use function Sys.Date() to find out the current date and Sys.Date()- 15 to calculate the date located 15 days in the past; 2) note that the output of BatchGetSymbols is a list -- a special type of object -- and that the price data is located in the second element of that list.

Solution

if (!require(BatchGetSymbols)) install.packages('BatchGetSymbols')

l_out <- BatchGetSymbols(tickers = 'IBM',
                         first.date = Sys.Date() - 15,
                         last.date = Sys.Date())

df_prices <- l_out[[2]]
str(df_prices)
