---------------------------------------
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).
