>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: R
>            Reporter: Nic Crane
>            Priority: Major

> If I run:
>  
> {code:java}
> tab <- Table$create(name = rownames(mtcars), mtcars)
> match_arrow(Array$create("Valiant"), tab)
> {code}
>  
> I get `Error: Unrecognized vector instance for type ENVSXP`
> and if I run:
> {code:java}
> match_arrow(c("Valiant"), tab){code}
> I get `Error in match(x, table, ...) : 'match' requires vector arguments `
> This is because in both cases, input parameters are not of the expected type.  We should add type checking and user-friendly error messages that indicate this.
