Yu Ishikawa updated SPARK-10106:
--------------------------------
Description:
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}
