[jira] [Commented] (ARROW-13703) [Python][R] Add bindings for new dataset writing options

    [ https://issues.apache.org/jira/browse/ARROW-13703?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17415622#comment-17415622 ] 

Weston Pace commented on ARROW-13703:
-------------------------------------

[~npr] requested [here](https://github.com/apache/arrow/pull/10955#discussion_r709212523) that, when exposing these options to R, we change the R default for "existing_data_behavior" to be "kOverwriteOrIgnore" in order to maintain backwards compatibility.
