[jira] [Created] (ARROW-13370) [R] More special handling for known errors in arrow_eval

Neal Richardson created ARROW-13370:
---------------------------------------

             Summary: [R] More special handling for known errors in arrow_eval
                 Key: ARROW-13370
                 URL: https://issues.apache.org/jira/browse/ARROW-13370
             Project: Apache Arrow
          Issue Type: New Feature
          Components: R
            Reporter: Neal Richardson
             Fix For: 6.0.0


We have special handling in arrow_eval that looks for the "not supported in Arrow" error, and when that's found it shows the error message rather than swallowing it in an "Expression not supported" message. But we have other error messages we raise in nse_funcs that are worth showing--bad input etc. Use a sentinel error message that we can also detect and subclass as "arrow-try-error" like the others, or (better) raised a classed exception (if that's supported in all versions of R we support).
