Thanks, Michael. Appreciate it. But suppose I go for the plot, how to extract it from R ... say, I want to save it as a .png file. Regards, Preetam On Sun, Mar 6, 2016 at 3:39 PM, Michael Dewey <lists at dewey.myzen.co.uk> wrote:
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 On 06/03/2016 07:40, Preetam Pal wrote:
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
