> URL: https://issues.apache.org/jira/browse/SPARK-10106
> Project: Spark
> Issue Type: New Feature
> Components: SparkR

>
> Add a column function on a DataFrame like `ifelse` in R to SparkR.
> I guess we could implement it with a combination with {{when}} and
> {{otherwise}}.
> h3. Example
> If {{df$x > 0}} is TRUE, then return 0, otherwise return 1.
> {noformat}
> ifelse(df$x > 0, 0, 1)
> {noformat}
