Neal Richardson created ARROW-9271: -------------------------------------- Summary: [R] Preserve data frame metadata in round trip Key: ARROW-9271 URL: https://issues.apache.org/jira/browse/ARROW-9271 Project: Apache Arrow Issue Type: Improvement Components: R Reporter: Neal Richardson Fix For: 2.0.0
ARROW-8899 collects R attributes from the columns of a data.frame (including recursively in data frame columns), adds them to arrow schema metadata, and restores them when pulling a data frame into R. However, any attributes on the outer data frame itself are not preserved. These are lost in some autosplice magic code before {{AddMetadataFromDots}} can collect it. -- This message was sent by Atlassian Jira (v8.3.4#803005)
