exceptAll: exceptAll

In SparkR: R Front End for 'Apache Spark'

Description

Return a new SparkDataFrame containing rows in this SparkDataFrame but not in another SparkDataFrame while preserving the duplicates. This is equivalent to EXCEPT ALL in SQL. Also as standard in SQL, this function resolves columns by position (not by name).

Usage

exceptAll(x, y)

## S4 method for signature 'SparkDataFrame,SparkDataFrame'
exceptAll(x, y)

Arguments

x	a SparkDataFrame.
y	a SparkDataFrame.

Value

A SparkDataFrame containing the result of the except all operation.

Note

exceptAll since 2.4.0
