-----------------------------------
Summary: Add `ifelse` Column function to SparkR
Key: SPARK-10106
URL: https://issues.apache.org/jira/browse/SPARK-10106
Project: Spark
Issue Type: New Feature
Components: SparkR
Reporter: Yu Ishikawa
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$x > 0}} is TRUE, then return 0, else return 1.
{noformat}
ifelse(df$x > 0, 0, 1)
{noformat}
