Dear all,    

I have an annual time-series of population numbers and I would like to estimate the auto-correlation. Can I use acf() function and judge whether auto-correlation is significant by the plots? The acf array produced by this functions gives the auto-correlation at lags 1, 2.... Is that right?      

Thank you!
