Yu Ishikawa commented on SPARK-8431:
------------------------------------
Hi [~shivaram] and [~davies], thank you for your comment.
In {{sql/core/src/main/scala/org/apache/spark/sql/Column.scala}}, I implemented
the {{in}} operation like below. However I don't know What Java class the
parameter {{Any*}} is.
https://github.com/apache/spark/pull/6824/files#diff-ac415c903887e49486ba542a65eec980R624
{noformat}
def in(list: Any*): Column = In(expr, list.map(lit(_).expr))
{noformat}
Umm, should we add a wrapper method like below to call by SparkR?
{noformat}
def in(list: List[Any]): Column = in(list:_*)
{noformat}
> Add in operator to DataFrame Column in SparkR
