> R is flexible when it comes to integer vs. floating point, generally obscuring the details inside a "numeric" class, but it knows how to make it seem like my integer-looking data stored in a double is actually integer. This means that an R user can think they have integers even when the underlying storage is not. 
> So I would have expected this to work, and indeed to be one reason I'd want to specify a schema when creating a table:
> {code:r}
> > table(a = 1, schema = schema(a = int32()))
> Error in Table__from_dots(dots, schema) : 
>   Invalid: Cannot convert R vector of type REALSXP to integer Arrow array
> {code}
