To create a stock returns dataset using R, you can follow these steps:


Step 1: Install the necessary packages

1
install.packages("quantmod")


Step 2: Load the required libraries

1
library(quantmod)


Step 3: Set the start and end dates for the desired time period

1
2
start_date <- "2020-01-01"
end_date <- "2020-12-31"


Step 4: Define the ticker symbol of the stock you want to analyze

1
ticker <- "AAPL"


Step 5: Download the stock data using getSymbols function from the quantmod package

1
getSymbols(ticker, from = start_date, to = end_date)


Step 6: Extract the stock's closing prices from the downloaded data

1
stock_prices <- Cl(get(ticker))


Step 7: Calculate the daily returns using the diff function

1
stock_returns <- diff(log(stock_prices))


Step 8: Create a data frame to store the stock returns data

1
returns_data <- data.frame(Date = index(stock_returns), Returns = coredata(stock_returns))


Now you have a dataset (returns_data) that consists of the date and corresponding stock returns. You can further manipulate or analyze this data using various statistical or visual tools available in R.
