R Program to add a new item to a given list

How to add a new item to a given list

Here we are explaining how to write an R program to add a new item to a given list. Here we are using the given list for adding new items. The use of the $ symbol helps to specify the new item along with the list.

df$x

Where x indicates the position or element of the list df.

How to add a new item to a given list in the R program

Below are the steps used in the R program to add a new item to a given list. In this R program, we directly give the values to a list by specifying the element with the position. Consider the variable L1 which holds the list elements. And here adding a new element to the position x4.

ALGORITHM

STEP 1: Assign variables L1  with a list

STEP 2: Print the original lists

STEP 3: Add a new element to the list as  L1$x4 = "Banana"

STEP 4: Print the final list L1

R Source Code

                                          L1 = list(x1 = 1:5, x2 = "Apple", x3 = "Mango")
print("Original list:")
print(L1)
print("Add a new vector to the list:")
L1$x4 = "Banana"
print(L1)
                                      

OUTPUT

[1] "Original list:"
$x1
 [1]  1  2  3  4  5  

$x2
[1] "Apple"

$x3
[1] "Mango"

[1] "Add a new vector to the list:"
$x1
 [1]  1  2  3  4  5  

$x2
[1] "Apple"

$x3
[1] "Mango"

$x4
[1] "Banana"
