Hi R,

 

I have doubt. 

 

>x= c(4,5,6,3,2,4,5)

>acf(x,plot=F,lag.max=1)

 

Autocorrelations of series 'x', by lag

 

    0     1 

1.000 0.182 

 

But if I actually calculate the autocorrelation at lag1 I get,

 

>cor(x[-1],x[-length(x)])

[1] 0.1921538

 

Even in excel I get 0.1921538 value. So, I want to know what the 'acf'
function is calculating here....

 

Thanks in advance,

Shubha Karanth
