Ian Cook created ARROW-12292: -------------------------------- Summary: [R] Reconsider behavior of as.<type>.ArrowDatum functions Key: ARROW-12292 URL: https://issues.apache.org/jira/browse/ARROW-12292 Project: Apache Arrow Issue Type: Improvement Components: R Reporter: Ian Cook Assignee: Ian Cook
As discussed at [https://github.com/apache/arrow/pull/9942#issuecomment-815315840,] the {{as.double()}}, {{as.integer()}}, and {{as.character()}} methods for {{ArrowDatum}} return R vectors of the specified R types, whereas in dplyr, these same functions perform casts to the analogous Arrow types Compare the definitions: * {{ArrowDatum}} methods: [https://github.com/apache/arrow/blob/ace2bfc160e049b4edc7ffb55081cfb7210d6e43/r/R/arrow-datum.R#L139-L145] * dplyr functions: [https://github.com/apache/arrow/blob/f2db785c24015b102db9b268c67a6ea73c5d7e93/r/R/dplyr.R#L399-L432] Consider whether the {{ArrowDatum}} methods should instead perform casts but keep the data in Arrow so that the user would have to also call {{as.vector()}} to return the data as an R vector. -- This message was sent by Atlassian Jira (v8.3.4#803005)
