Since it's an array (obviously inside a list, say L), you can index is
like an array:
L$acf[,,1] # for the first matrix of the third dimension
L$acf[,1,] # for the first matrix of the second dimension
# in other words: all 1st columns
L$acf[4,,] # for the fourth matrix of the first dimension
# in other words: all 4th rows
See the manuals for details on indexing arrays.
