--------------------------------------

             Summary: [R] array() needs to take single input, not ...
                 Key: ARROW-4560
                 URL: https://issues.apache.org/jira/browse/ARROW-4560
             Project: Apache Arrow
          Issue Type: Improvement
          Components: R
            Reporter: Romain François
            Assignee: Romain François


The `array()` factory takes `...` and this makes this harder than it needs to 
be because then we have two competing views on type: 

 - `vctrs::vec_c(.ptype=)` which uses R specific typing system

 - the arrow type 

 

So `array()` should really take a single thing for `data`, which may be the 
result of a `vctrs::vec_c(...)` if we do want R type promotion.
