R help - Apr 2003 - SARIMA

I'm trying to fit a SARIMA(p,d,q)x(P,D,Q) with seasonal period s to some
data. When dealing with these types of models one often looks at the ACF and
PACF of the time series at lags that are multiples of s, to identify potential
values of P, Q. How would I do this in R given the original time series?
Secondly given a time series x acf(x) just gives me the plot of the acf. How
would I actually get the actual numeric values at each lag?Thanks in advance.N

?acf: note there is a Value: section and your assertion is incorrect.
