Get difference of dataframes using Dplyr in R

In this article, we will discuss How to find the difference between two dataframes using the Dplyr package in the R programming language.

Set difference refers to getting or extracting those values from one dataset that are not present in the other. For this, dplyr supports a function called setdiff(). setdiff() is used to return the data present in the first dataframe but not present in the second dataframe.

Syntax:

setdiff(dataframe1,dataframe2)

Example 1: R program to perform setdiff() operation of the second dataframe with the first dataframe

R

library(dplyr)

# create dataframe1 with college
# 1 data
data1=data.frame(id=c(1,2,3,4,5),

                 name=c('sravan','ojaswi','bobby',
                        'gnanesh','rohith'))

# create dataframe1 with college
# 2 data
data2=data.frame(id=c(1,2,3,4,5,6,7),

                 name=c('sravan','ojaswi','bobby',
                        'gnanesh','rohith',
                        'pinkey','dhanush'))

# set difference of second dataframe
# and first dataframe
print(setdiff(data2,data1))

Output:

Example 2: R program to perform setdiff() operation of the first dataframe with the second dataframe

R

library(dplyr)

# create dataframe1 with college

                 name=c('sravan','ojaswi','bobby',
                        'gnanesh','rohith'))

# create dataframe1 with college
# 2 data
data2=data.frame(id=c(1,2,3,4,5,6,7),

                 name=c('sravan','ojaswi','bobby',
                        'gnanesh','rohith',
                        'pinkey','dhanush'))

# set difference of first dataframe
# and second dataframe
print(setdiff(data1,data2))

Output:
