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
