> *Steps*
>  * Read about ExecPlan and ExecPlan::ToString
>  ** https://issues.apache.org/jira/browse/ARROW-14233
>  ** https://issues.apache.org/jira/browse/ARROW-15138
>  ** https://issues.apache.org/jira/browse/ARROW-13785
>  * Hook up to the existing C++ ToString method for ExecPlans 
>  * Implement a {{ToString()}} method for {{ExecPlan}} R6 class
>  * Implement and document {{show_exec_plan()}}
> {*}Original description{*}:
> Now that we can print a query plan (ARROW-13785) we should wire this up in R so we can see what execution plans are being put together for various queries (like the TPC-H queries)
