Davies Liu commented on SPARK-10079:
------------------------------------

There are two public  col/column function in Scala and Python, which return an 
Column from colName, I think this one is useful, could be added into SparkR. 

> Make `column` and `col` functions be S4 functions

> {{column}} and {{col}} function at {{R/pkg/R/Column.R}} are currently defined
