[GitHub] [arrow] rtpsw commented on pull request #13397: ARROW-16444: [R] Implement user-defined scalar functions in R bindings

rtpsw commented on PR #13397:

   > Another comment on the function registration is that if you try to run the test cases twice, you will get a test failure saying the function is already registered. In R, is there a way to scope the test case such that the changed function registry doesn't affect the following test cases. I guess at some point the function unregistration needs to be handled. Or there is an [interesting discussion going on about it in another PR](https://github.com/apache/arrow/pull/13375#issuecomment-1156905723).
   
   More details about the nested/scoped registries approach in [this post](https://issues.apache.org/jira/browse/ARROW-16823?focusedCommentId=17554982&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17554982).
