arrange() method
In R, the arrange() method is used to order the rows based on a specified column. The syntax of arrange() method is specified below-
arrange(dataframeName, columnName)
Example:
In the below code we ordered the data based on the runs from low to high using arrange() function.
R
# import dplyr packagelibrary(dplyr)# create a data frame stats <- data.frame(player=c('A', 'B', 'C', 'D'), runs=c(100, 200, 408, 19), wickets=c(17, 20, NA, 5))# ordered data based on runsarrange(stats, runs) |
Output
player runs wickets 1 D 19 5 2 A 100 17 3 B 200 20 4 C 408 NA
Data Manipulation in R with Dplyr Package
In this article let’s discuss manipulating data in the R programming language.
In order to manipulate the data, R provides a library called dplyr which consists of many built-in methods to manipulate the data. So to use the data manipulation function, first need to import the dplyr package using library(dplyr) line of code. Below is the list of a few data manipulation functions present in dplyr package.
