 Summary: [R] is.nan() evaluates to null on Arrow null values
 Key: ARROW-12850
 URL: https://issues.apache.org/jira/browse/ARROW-12850
 Project: Apache Arrow
  Issue Type: Improvement
  Components: R
Reporter: Ian Cook


{code}
> is.nan(NA_real_)
[1] FALSE 

> as.vector(is.nan(Scalar$create(NA_real_)))
[1] NA
{code}
There is a discrepancy here between the {{FALSE}} result in R and the {{null}} 
result in Arrow (which results in {{NA_logical_}} when converted to an R 
vector).

I don't think the {{is.nan}} C++ kernel should change here because this is just 
a quirk of R. For example, NumPy and pandas is consistent with the Arrow C++:
{code}
> np.isnan(pd.NA)

{code}
We could maybe consider adding a boolean option to the {{is.nan}} C++ kernel to 
control whether to consider nulls as {{NaN}}.

The type signature would look like this:

[jira] [Created] (ARROW-12848) [Release] Mail template points to 404

 Summary: [Release] Mail template points to 404
 Key: ARROW-12848
 URL: https://issues.apache.org/jira/browse/ARROW-12848
 Project: Apache Arrow
  Issue Type: Improvement
  Components: Developer Tools
Reporter: Jorge Leitão


The email template to send to the dev for vote yields

{code:java}
[4]: https://apache.jfrog.io/artifactory/arrow/centos-rc/4.0.1-rc1
[5]: https://apache.jfrog.io/artifactory/arrow/debian-rc/4.0.1-rc1
[6]: https://apache.jfrog.io/artifactory/arrow/python-rc/4.0.1-rc1
[7]: https://apache.jfrog.io/artifactory/arrow/ubuntu-rc/4.0.1-rc1
{code}

however, these are always 404, as the distros are directory-based. This should 
probably be without `/4.0.1-rc1`, since the 4.0.1-rc1 is split between the 
different sub-directories.
