Thanks for the advice. I guess I should have read the acf help page more thoroughly to appreciate the role of plot.acf(). Typical. Thanks Duncan.

If you read ?plot.acf, you'll see how it comes up with acf settings: the global ones are overridden for data like yours. You might want to do some experimenting and suggest better defaults for plot.acf.
