Hello,

I am calling the auto.arima method in the forecast package at it returns what 
seems to be valid Arima output. But when I feed this output to 'predict' I get:

Error in predict.Arima(catall.fit[[.index]], n.ahead = 12) : 
  'xreg' and 'newxreg' have different numbers of columns

Is there a way to tell what is being supplied to xreg from the Arima output? 

Any ideas?

Thank you.

Kevin
