Hi list,
I have a set of data which I want to use time series analysis in R in order
to forecast the value for future. I know there are some R functions, but not
sure how to use them. Would you please help me if you are familiar with time
series in R? I want to get value for Nov 2012 using the following data.

thanks
Alireza
