According to the documentation acf returns what you want. It also says that it returns it invisibly if plot = TRUE which I imagine is what you are doing.

So try

res <- acf(insert_parameters_here, plot = FALSE)

and then look at res

Hi R-users,

I have a time series of residuals and I want to get the ACF
(autocorrelation) values till lag = 12, along with the 12 upper/lower
confidence limits. I understand that acf(residual) would give me the plot,
but I will also need the actual values as an array etc. Plus, I'll have to
extract the plot from R as well. Is there a way to achieve these two?

Appreciate your help.

Regards,
Preetam
