--------------------------------------
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.
