Raw prices are rarely used directly in statistical modeling because they are non-stationary. Analysts convert prices into log returns or discrete returns to achieve stationarity.
# Historical Value at Risk calculation at 95% confidence VaR_95 <- tibbletime::as_tbl_time(returns, index = date) %>% tq_performance(Ra = log_returns, PerformanceFun = VaR, p = 0.95, method = "historical") Use code with caution.

Most financial data (prices, rates, volumes) is sequential. R’s xts and zoo objects handle irregular time series effortlessly.
stocks <- c("JPM", "WMT") %>% tq_get(get = "stock.prices", from = "2020-01-01", to = "2023-12-31") %>% tq_transmute(select = adjusted, mutate_fun = periodReturn, period = "daily")
