[jira] [Commented] (ARROW-4600) [Ruby] Arrow::DictionaryArray#[]
should returns the item in the indices array
[ https://issues.apache.org/jira/browse/ARROW-4600?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16770700#comment-16770700 ]
Kouhei Sutou commented on ARROW-4600:
-------------------------------------
This error is unrelated.
{{%w[foo bar baz]}} should be {{Arrow::StringArray.new(%w[foo bar bz])}}.
