Nicola Crane updated ARROW-14457:
---------------------------------
    Description: 
This difference in behaviour between base R and Arrow should be documented

{code:r}
> c(1*2) * c(3,4)
[1] 6 8

> Array$create(c(1,2)) * Array$create(c(3,4))
Array
<double>
[
  3,
  8
]

> Array$create(c(1,2)) * c(3,4)
 Error: NotImplemented: Function multiply_checked has no kernel matching input types (array[double], scalar[list<item: double>])
