Re: [R] time series, longitudinal data or trajectories

Thanks for yours answers. So if I understand: - Trajectories are continuous, the other are discrete. - The difference between time series and longitudinal is that time series are made at regular time whereas longitudinal are not ? - Repeated measures are over a short period of time. So if I
