I have sales data for years 2011, 2012 and upto september 2013. I have applied the decompose function to filter the trend , seasonal and random component. however i would like to apply the predict function to forecast the sales for the rest of year and into 2014. How can i establish the order of the time series so as to fit ARIMA.
