> Add higher order functions API to SparkR
> ----------------------------------------
>
> Key: SPARK-30682
> URL: https://issues.apache.org/jira/browse/SPARK-30682
> Project: Spark
> Issue Type: Improvement
> Components: SparkR, SQL
> Affects Versions: 3.0.0
> Reporter: Maciej Szymkiewicz
> Assignee: Maciej Szymkiewicz
> Priority: Major
>
> As of 3.0.0 higher order functions are available in SQL and Scala, but not in SparkR forcing R users to invoke these through {{expr}}, {{selectExpr}} or {{sql}}.
> It would be great if Spark provided high level wrappers that accept plain R functions operating on SQL expressions.
