Print the Value of an Object in R Programming - identity() Function

Last Updated : 16 Jun, 2020

identity() function in R Language is used to print the value of the object which is passed to it as argument.

Syntax: identity(x) Parameters: x: An Object

Example 1:

Python3 1==

# R program to print
# the value of an object

# Creating a vector
x <- c(1, 2, 3, 4)

# Creating a list
list1 <- list(letters[1:6]) 

# Calling the identity function
identity(x)
identity(list1)

Output:

[1] 1 2 3 4
[[1]]
[1] "a" "b" "c" "d" "e" "f"

Example 2:

Python3 1==

# R program to print
# the value of an object

# Calling predefined data frame
x1 <- BOD

# Creating a matrix
mat <- matrix(c(1:9), 3, 3, byrow = T)

# Calling the identity() Function
identity(x1)
identity(mat)

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
     [, 1] [, 2] [, 3]
[1, ]    1    2    3
[2, ]    4    5    6
[3, ]    7    8    9
