Adding elements in a vector in R programming – append() method

The append() function in R is used to insert values into a vector at a specified position. If no position is mentioned, the values are added at the end of the vector.

Syntax:

append(x, value, index(optional))

Return Value: It returns a new vector with the specified values appended.

Example 1: Appending a Value at the End of a Vector

vec <- c(2, 4, 6, 8)

# Appending value 12 to the vector
result <- append(vec, 12)

print(result)

Output:

[1]  2  4  6  8 12

Example 2: Inserting a Value at a Specific Position

vec <- c(5, 10, 15, 20)

# Inserting 7 at the second position
result <- append(vec, 7, after = 1)

print(result)

Output:

[1]  5  7 10 15 20
