[jira] [Created] (ARROW-6337) [R] as_tibble in R API is a misnomer

James Lamb created ARROW-6337:
---------------------------------

             Summary: [R] as_tibble in R API is a misnomer
                 Key: ARROW-6337
                 URL: https://issues.apache.org/jira/browse/ARROW-6337
             Project: Apache Arrow
          Issue Type: Improvement
          Components: R
            Reporter: James Lamb


As of ARROW-5190, the R package's dependency on *tibble* has been moved from *Imports* to *Suggests*. However, this signature of *read_parquet(), read_delim_arrow(), read_json_arrow(),* and *read_feather()* all still have an argument called "as_tibble".

Per [this comment|[https://github.com/apache/arrow/pull/4454#issuecomment-500563214],] the argument "as_tibble" is a misnomer. If that argument is given a TRUE, those functions will return a data.frame, not a tibble. I agree with Neal's comment...I think that instead of changing return type based on a boolean, it would be better for all the *read_** functions to return a data.frame and for other types of operations to get their own functions.

I think it's important to consider this type of user-facing breaking change _now_ while the R package's version is still 0.x.

As always, thanks for hearing me out!
