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.
