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.

[R] ACF values with confidence limits + Plot Extaction
a <- as.ts(rnorm(20))
png("acf.png")
a.acf <- acf(a)
dev.off()
# to see what is available
names(a.acf)
unclass(a.acf)

Thank you very much,Jean-Claude and Michael. 1> @Michael, your suggestion "plot = FALSE" only returns the estimated ACF values, not the confidence limits at different lags. May be I am missing something here.Do you know any way around for this? 2>@Jean-Claude, got it, thanks.

My word! Did you try ?png ? More to the point, any good R tutorial should provide such info. Pls make some reasonable efforts on your own before posting here.
