Does the following do what you want? You often
need to use aperm() to permute the dimensions of
apply()'s output.
> a <- array(2^(0:23), dim=c(2,3,4))
> aperm(apply(a, 1:2, cumsum), c(2,3,1))
, , 1
[,1] [,2] [,3]
[1,]14 16
[2,]28 32
, , 2
[,1] [,2] [,3]
[1,] 65
Hi:
Could you supply a small reproducible example with the output that you
expect? For example, what output would you expect from the following:
a <- array(1:24, c(2, 2, 3))
?

Thank you for your time and help.
I'm quite aware that this problem seems as basic stuff, and of course I've
read several R and matlab manuals, and also consulted the D. Hiebeler,
Matlab / R Reference and several others, but none of the suggested solutions
seems to give me the right result.
