How to create an Empty Vector in R - Step by Step Examples

How to create an Empty Vector in R ?

Answer

To create an empty vector in R, you can use the vector function with the appropriate type and length, or you can use the c function without any arguments.


✐ Examples

1 Create an Empty Numeric Vector

In this example,

  1. We use the vector function to create an empty vector.
  2. The first argument to the vector function is the type of the vector, which in this case is numeric.
  3. The second argument is the length of the vector, which we set to 0 to indicate that it is empty.
  4. We assign the result to a variable named empty_numeric_vector.
  5. Finally, we print the empty_numeric_vector to the console to verify that it is indeed empty and of type numeric.

R Program

empty_numeric_vector <- vector("numeric", length = 0)
print(empty_numeric_vector)

Output

numeric(0)

2 Create an Empty Character Vector

In this example,

  1. We use the vector function to create an empty vector.
  2. The first argument to the vector function is the type of the vector, which in this case is character.
  3. The second argument is the length of the vector, which we set to 0 to indicate that it is empty.
  4. We assign the result to a variable named empty_character_vector.
  5. Finally, we print the empty_character_vector to the console to verify that it is indeed empty and of type character.

R Program

empty_character_vector <- vector("character", length = 0)
print(empty_character_vector)

Output

character(0)

3 Create an Empty Vector Using the c Function

In this example,

  1. We use the c function without any arguments to create an empty vector.
  2. The c function is used to combine values into a vector, and when called without arguments, it creates an empty vector.
  3. We assign the result to a variable named empty_vector.
  4. Finally, we print the empty_vector to the console to verify that it is indeed empty.

R Program

empty_vector <- c()
print(empty_vector)

Output

NULL
