setdiff() function in R Programming Language is used to find the elements which are in the first Object but not in the second Object.

Syntax: setdiff(x, y)

Parameters: 

  • x and y: Objects with sequence of items

R – setdiff() Function Example

Example 1: Apply setdiff to Numeric Vectors in R Language

R




# R program to illustrate
# the use of setdiff() function
   
# Vector 1
x1 <- c(1, 2, 3, 4, 5, 6, 5, 5)   
   
# Vector 2 
x2 <- c(2:4)    
   
# Calling setdiff() Function
x3 <- setdiff(x1, x2)      
   
print(x3)                

Output: 

[1] 1 5 6

Example 2: Apply setdiff to Character Vectors in R Language

R




# R program to illustrate
# the use of setdiff() function
   
# Vector 1
x <- c("GFG", "GEEKS")   
   
# Vector 2 
y <- c("GFG", "Welcome", "HOME")    
   
# Calling setdiff() Function
x3 <- setdiff(x, y)      
   
print(x3)                

Output:

[1] "GEEKS"

Example 3: setdiff Between R Dataframes

R




# R program to illustrate 
# the use of setdiff() function
   
# Data frame 1
data_x <- data.frame(x1 = c(5, 6, 7),    
                     x2 = c(2, 2, 2))
   
# Data frame 2
data_y <- data.frame(y1 = c(2, 3, 4),       
                     y2 = c(2, 2, 2))
   
# Calling setdiff() Function
data_z <- setdiff(data_x, data_y)  
   
print(data_z)

Output: 

  x1
1  5
2  6
3  7
