How to Insert an Item at Specific Index in a Vector in R ?

Answer

To insert an item at a specific index in a vector in R, you can use the append() function. This function allows you to append elements to a vector at a specified position.

✐ Examples

1 Insert an Integer at Specific Index in a Vector

In this example,

Create a vector of integers using the c() function.
Declare an integer variable to insert into the vector.
Use the append() function to insert the integer at the desired index.
After insertion, you can verify the contents of the vector.

R Program

# Create a vector of integers
numbers <- c(1, 2, 3, 4, 5)

# Declare an integer to insert
new_number <- 10

# Index to insert
index <- 3

# Insert the integer at the desired index
numbers <- append(numbers, new_number, after = index - 1)

# Print the updated vector
print(numbers)

Output

[1]  1  2 10  3  4  5

2 Insert a String at Specific Index in a Vector

In this example,

Create a vector of strings using the c() function.
Declare a string variable to insert into the vector.
Use the append() function to insert the string at the desired index.
After insertion, you can verify the contents of the vector.

R Program

# Create a vector of strings
words <- c("apple", "banana", "orange")

# Declare a string to insert
new_word <- "grape"

# Index to insert
index <- 2

# Insert the string at the desired index
words <- append(words, new_word, after = index - 1)

# Print the updated vector
print(words)

Output

[1] "apple"  "grape"  "banana" "orange"
