Hi R users, I am doing cross correlation analysis on 2 time series (call them y-series and x-series) where I need the use the model developed on the x-series to prewhiten the yseries.. Can someone point me to a function/filter in R that would allow me to do that? Thanks in advance for any help!

if you want to whiten the series why not just new series <- rnorm(num.obs)+series

Look in the package "forecast" for the function "Arima". It will do what you want. It's different than arima function in the stats package. Bob
