# except

Return a new SparkDataFrame containing rows in this SparkDataFrame but
not in another SparkDataFrame. This is equivalent to `EXCEPT DISTINCT`
in SQL.

## Usage

``` r
except(x, y)

# S4 method for class 'SparkDataFrame,SparkDataFrame'
except(x, y)
```

## Arguments

  - x:
    
    a SparkDataFrame.

  - y:
    
    a SparkDataFrame.

## Value

A SparkDataFrame containing the result of the except operation.

## Note

except since 1.4.0
