[R] ts acf accessing to values

[juli g. pausas]

Hi,
I don't quite understant how can I access to the acf values from the
list produced by the acf function
Example:

library(ts)
t <- acf(ts.union(ts(1:10), ts(11:20)))
t$acf
> tmp$acf
, , 1

            [,1]        [,2]
[1,]  1.00000000  1.00000000
[2,]  0.70000000  0.70000000
[3,]  0.41212121  0.41212121
[4,]  0.14848485  0.14848485
[5,] -0.07878788 -0.07878788
[6,] -0.25757576 -0.25757576
[7,] -0.37575758 -0.37575758

, , 2

            [,1]        [,2]
[1,]  1.00000000  1.00000000
[2,]  0.70000000  0.70000000
[3,]  0.41212121  0.41212121
[4,]  0.14848485  0.14848485
[5,] -0.07878788 -0.07878788
[6,] -0.25757576 -0.25757576
[7,] -0.37575758 -0.37575758

Any help on how can I access to the vector with the acf values?
Or perhaps I misusing the acf function ....
Thanks in advance

Juli
