Combine vectors in R using vectorization where values only sum if they are not equal

Question

I have two vectors that I need to add together, but only in instances where their corresponding values are not equal. Ex:

aa <- c(1,0,0,1,0)
bb <- c(0,1,1,1,0)

I want to generate a combined vector like so:

aa <- c(1,1,1,1,0)

How might I go about doing this, particularly with vectorization?

`inds = xor(aa, bb); replace(aa, inds, aa[inds] + bb[inds])` — d.b, Oct 23 '20 at 01:41

Looks like you are trying to implement the OR gate .You can use pmax :

pmax(aa, bb)
#[1] 1 1 1 1 0
