But the problem isn't the language, it is the algorithm. For example, univariate and methods in R are not designed for handling time series data. To do so, you must scale your observations to an annual scale by raising the compound return to the number of periods in a year, and taking the root to the number of total observations: If you missed the first post and want to start at the beginning with calculating portfolio volatility, have a look here - Introduction to Volatility.
