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!
