Vladimir created ARROW-16641: -------------------------------- Summary: [R] How to filter array columns? Key: ARROW-16641 URL: https://issues.apache.org/jira/browse/ARROW-16641 Project: Apache Arrow Issue Type: Wish Components: R Reporter: Vladimir Fix For: 8.0.0
In the parquet data we have, there is a column with the array data type ({*}list<array_element <string>>{*}), which flags records that have different issues. For each record, multiple values could be stored in the column. For example, `{_}[A, B, C]{_}`. I'm trying to perform a data filtering step and exclude some flagged records. Filtering is trivial for the regular columns that contain just a single value. E.g., {{flags_to_exclude <- c("A", "B")}} {{datt %>% filter(! col %in% flags_to_exclude)}} Given the array column, is it possible to exclude records with at least one of the flags from `flags_to_exclude` using the arrow R package? I really appreciate any advice you can provide! -- This message was sent by Atlassian Jira (v8.20.7#820007)
