I think you are looking for subscripting with a
matrix:
x[cbind(1,1,2)]
See, for instance, the subscripting section of chapter 1
of S Poetry.

Hi
Is it possible to subset an n-dimensional array by a vector of n
dimensions? E.g. assume I have
x <- array(1:24, dim=2:4)
x[1,1,2]
[1] 7
dims <- c(1,1,2)
I would like a function that I can supply x and dims as parameters to,
and have it return 7. Also, I would like to do something like:
x[1,1,]
[1] 1 7 13 19
dims2<- c(1,1,NA)
And have a function of x and dims2 that gives me back [1] 1 7 13 19
Does such a thing exist?
Thanks
Richard
