------------------------------------
Summary: Add crosstab to SparkR DataFrames
Key: SPARK-8364
URL: https://issues.apache.org/jira/browse/SPARK-8364
Project: Spark
Issue Type: New Feature
Components: SparkR
Reporter: Xiangrui Meng
Assignee: Xiangrui Meng
Add `crosstab` to SparkR DataFrames, which takes two column names and returns a
local R data.frame. This is similar to `table` in R. However, `table` in SparkR
is used for loading SQL tables as DataFrames. The return type is data.frame
instead table for `crosstab` to be compatible with Scala/Python.
