acf question...

Then you are posting in the wrong forum, since this is a forum about getting R to do things for which you already understand the theory.

As to the results you are getting, I highly recommend reading the details section of ?ccf.

BTW The Posting Guide indicates that you should post in text format because HTML mutilates R code. This is a setting in your email program.

I am trying to understand lagged correlations. 
?
x= 1:100; 
y = c(rep(NA,40), 1:60)ccf(x = x, y = y, lag.max=100,
na.action=na.pass, type = "correlation") 
?
I was hoping to see max cor at lag = 40. But I am not. What am I doing
wrong?
?
Thanks
