[jira] [Created] (ARROW-11589) [R] Add methods for modifying Schemas

Neal Richardson created ARROW-11589:
---------------------------------------

             Summary: [R] Add methods for modifying Schemas
                 Key: ARROW-11589
                 URL: https://issues.apache.org/jira/browse/ARROW-11589
             Project: Apache Arrow
          Issue Type: New Feature
          Components: R
            Reporter: Carl Boettiger
             Fix For: 4.0.0


$<-, [[<-, and (probably) [<- methods. We have the extracting versions implemented but not the updating ones, and that would be useful.

Motivating use case: schema detection for a dataset misreads a column, so take the autodetected schema, modify one field, and then re-create the dataset with the correct schema.
