how to fit the auto arima model

#1
hi guys,

Im new to R and I got a problem unsolved for several days:

I got a dataset which covers three years by week and I ran an auto arima on the train data set which is 80% of the original data set. Then I got the following result: ARIMA(1,0,0)(0,1,0)[53] with drift

Im wondering how to apply this model on my entire data set, since it is not in a regular format of single q, d, p parameters. Please kindly provide me a possible script in R.

Great thanks!
