[GitHub] [arrow] nealrichardson commented on pull request #13541: ARROW-15016: [R] `show_exec_plan` for an `arrow_dplyr_query`

   @dragosmg check out https://github.com/apache/arrow/pull/13397#discussion_r926785889. I think this explains why "the filter node is gone" on the head queries--it gets evaluated 🙀 inside of Build(). For now we should probably not try to show the query `if (is_collapsed(.data) && has_head_tail(.data$.data))` because that will cause the inner query to evaluate. We can back that out after ARROW-16628, I believe (should add a comment pointing to that issue too).
