[jira] [Comment Edited] (ARROW-11468) [R] Allow user to pass schema to read_json_arrow()

    [ https://issues.apache.org/jira/browse/ARROW-11468?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17314899#comment-17314899 ]

I think that's right. It should be relatively straightforward to pass through {{schema}} similarly to how {{newlines_in_values}} is passed through.

> The {{read_json_arrow()}} function lacks a {{schema}} argument, and it is not possible to specify a schema through {{JsonParseOptions}}. PyArrow allows the user to pass a schema to {{read_json()}} through {{ParseOptions}} to bypass automatic type inference. Implement this in the R package.
