--------------------------------------

             Summary: [R] Allow Scanner$create() to accept filter / project even with arrow_dplyr_querys
                 Key: ARROW-13560
                 URL: https://issues.apache.org/jira/browse/ARROW-13560
             Project: Apache Arrow
          Issue Type: Bug
          Components: R
            Reporter: Jonathan Keane
            Assignee: Jonathan Keane


Currently, when calling {{Scanner$create()}} on an {{arrow_dplyr_query}} the `projection` and `filter` arguments are ignored silently (since the dplyr query filters should be applied). 

This is helpful for predicate pushdowns 

One proposal is at https://gist.github.com/hannesmuehleisen/61d655bb345e0af374d10ca303894eef
