Reordering of a Data Set in R Programming - arrange() Function

Last Updated : 15 Jun, 2020

arrange() function in R Language is used for reordering of table rows with the help of column names as expression passed to the function.

Syntax: arrange(x, expr) Parameters: x: data set to be reordered expr: logical expression with column name

Example 1:

Python3 1==

# R program to reorder a data set 

# Loading library
library(dplyr)

# Calling dataset
x <- BOD
x

# Calling arrange() function
arrange(x, demand)

Output:

  Time demand
1    1    8.3
2    2   10.3
3    3   19.0
4    4   16.0
5    5   15.6
6    7   19.8
  Time demand
1    1    8.3
2    2   10.3
3    5   15.6
4    4   16.0
5    3   19.0
6    7   19.8

Example 2:

Python3 1==

# R program to reorder a data set 

# Loading library
library(dplyr)

# Create a data frame 
d <- data.frame( name = c("Abhi", "Bhavesh", "Chaman", "Dimri"),  
                 age = c(7, 5, 9, 16) ) 
  
# Arranging name according to the age 
d.name<- arrange(d, age) 
print(d.name)

Output:

     name age
1 Bhavesh   5
2    Abhi   7
3  Chaman   9
4   Dimri  16
