[jira] [Created] (ARROW-17460) [R] Don't warn if the new UDF I'm registering is the same as the existing one

Neal Richardson created ARROW-17460:
---------------------------------------

             Summary: [R] Don't warn if the new UDF I'm registering is the same as the existing one
                 Key: ARROW-17460
                 URL: https://issues.apache.org/jira/browse/ARROW-17460
             Project: Apache Arrow
          Issue Type: Improvement
          Components: R
    Affects Versions: 9.0.0
            Reporter: Neal Richardson


When you register a UDF, you get a warning if there already is a function with that name. This can be helpful, but it's a nuisance if you're running a script more than once interactively. I encountered this while working in an R Markdown document for a demo: the second time I rendered the doc in my R session, the warning was printed in the rendered document. 

It would be nice if we could determine that the UDF being registered is the same as the one that's already there and not warn in that case.
