[jira] [Updated] (ARROW-12055) [R] is.na() evaluates to FALSE on Arrow NaN values

     [ https://issues.apache.org/jira/browse/ARROW-12055?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ian Cook updated ARROW-12055:
-----------------------------
    Description: 
{code:java}
> is.na(NaN)
[1] TRUE 

> is.na(Scalar$create(NaN))
[1] FALSE{code}
FWIW, NumPy/pandas also behaves like R in this regard:
{code:java}
> pd.isna(np.nan)
True{code}

  was:
{code:java}
> is.na(NaN)
[1] TRUE 

> is.na(Scalar$create(NaN))
[1] FALSE{code}
