R Documentation

Arrange Rows by Variables

Description

Sort a SparkDataFrame by the specified column(s).

Usage

arrange(x, col, ...)

## S4 method for signature 'SparkDataFrame,Column'
arrange(x, col, ..., withinPartitions = FALSE)

## S4 method for signature 'SparkDataFrame,character'
arrange(x, col, ..., decreasing = FALSE, withinPartitions = FALSE)

## S4 method for signature 'SparkDataFrame,characterOrColumn'
orderBy(x, col, ...)

Arguments

x	a SparkDataFrame to be sorted.
col	a character or Column object indicating the fields to sort on
...	additional sorting fields
withinPartitions	a logical argument indicating whether to sort only within each partition
decreasing	a logical argument indicating sorting order for columns when a character vector is specified for col

Value

A SparkDataFrame where all elements are sorted.
