setequal() function in R Language is used to check if two objects are equal. This function takes two objects like Vectors, dataframes, etc. as arguments and results in TRUE or FALSE, if the Objects are equal or not.

Syntax: setequal(x, y)

Parameters:
x and y: Objects with sequence of items

Example 1:

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

# Vector 3
x3 <- c(2, 3, 4, 5, 6)
	
# Calling setequal() Function
setequal(x1, x2)	
setequal(x1, x3)	

Output:

[1] TRUE
[1] FALSE

Example 2:

# R program to illustrate
# the use of setequal() 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(5, 6, 7),		
					y2 = c(2, 2, 2))
	
# Calling setequal() Function
setequal(data_x, data_y)

Output:

[1] TRUE
