How to Insert an Element at Specific Index in a List in R ?

Answer

To insert an element at a specific index in a list in R, you can use the insert function from the magrittr package or manipulate list indices directly.

✐ Examples

1 Insert Element at Specific Index Using insert Function

In this example,

We create a list named numbers with initial integer values.
We use the insert function from the magrittr package to insert a new element at the desired index.
Finally, we print the updated list to standard output.

R Program

library(magrittr)
numbers <- c(1, 2, 3, 4, 5)
numbers <- insert(numbers, 3, 10)
print(numbers)

Output

[1]  1  2 10  3  4  5

2 Insert Element at Specific Index Manually

In this example,

We create a list named numbers with initial integer values.
We define the desired index and the new element.
We use list concatenation and indexing to insert the new element at the specified index.
Finally, we print the updated list to standard output.

R Program

numbers <- c(1, 2, 3, 4, 5)
index <- 3
element <- 10
updated_list <- c(numbers[1:(index-1)], element, numbers[index:length(numbers)])
print(updated_list)

Output

[1]  1  2 10  3  4  5
