Hello. I have been working on a project which involves random number generation and unit root test. After I generate the numbers (I am generating stock returns using rnorm(1000,0,0.25), I want to check if the series has a unit root or not. But before I should modify the data to time series. My question is which of the functions ts or timeSeries more appropriate to test unit root using Augmented Dickey Fuller test? Thank you.
