We do have internally `is_arrow_altrep()` (cf https://github.com/apache/arrow/blob/cc0606ff2a9bb53fddc8bdb31ccbdef45701fe8e/r/tests/testthat/test-altrep.R#L19) which could be exported if that's useful. Same thing with materialization, we have `test_arrow_altrep_force_materialize()` internally which could be used (or adapted) and exported. Would you be interested in working on a PR for one or both of those? > If I save this df to an RData file for sharing, then the RData file will not be readable in enviromnents without arrow installed. Though I will say that saving datasets to RData files like this is something we recommend against — for this reason but also they aren't particularly efficient, there's less cross language compatibility, etc. if you're using Arrow, I would recommend using Parquet (or in particular circumstances saving as arrow / IPC format) to disk. -- This is an automated message from the Apache Git Service.
