[R] array addition doesn't recycle!

[Tamas Papp]

Hi,

I have noticed the following:

> a <- array(1:4, c(2, 2))
> A <- array(1:4, c(2,2,2))
> A + a
Error in A + a : non-conformable arrays

It works with a matrix + a vector, why doesn't it work with arrays?
Am I missing something?

How would you do the above operation efficiently (ie I need to add a
matrix to each "plane" of 3-dim array)?  At the moment I am using
something like

A + array(a, c(2,2,2))

but it doesn't seem that efficient.

Thanks

Tamas
