title: Prediction using cross correlation model
body: <p>I'm pretty new in R and I'm working on a cross correlation model, I've searched for the answer but haven't been able to find it.</p>
  
  <p>I have been able to prove the cross correlation(lag correlation) between 2 time series using the R function with "ccf".</p>
  
  <p>Now based on the model created with ccf I want to be able to predict the next values of one of the variables based on the data of the other one. I don't seem to find information.</p>
  
  <p>This is relatively easy in auto-correlation with Arima, but I don't seem to be able to do it with the cross correlation.</p>
  
  <p>Any idea how can I achieve this?</p>
  
  <p>Thanks
  Fernando</p>
