Create a Vector of Zeros in R

In this tutorial, we will look at how to create a vector of zeros (having 0 as its elements) in R with the help of some examples.

How to create a vector of zeros in R?

There are multiple ways to create a vector for zeros. Some of the functions that can help you create a vector of zeros in R are – c(), integer(), numeric(), rep(), etc.

Let’s look at these methods with the help of examples.

Using the c() function

The c() function is used to combine different values (and/or vectors) into a vector. If you want to create a vector of zeros with a relatively smaller length, you can use the c() function.

For example, let’s use the c() function to create a vector of four zeros.

# create a vector of zeros
vec <- c(0, 0, 0, 0)
# display the vector
print(vec)

Output:

[1] 0 0 0 0

We get a vector of four zeros. Note that, manually typing zeros can become cumbersome when you want to create a vector of zeros of a larger length. In such cases, you can use the methods described below.

Using the integer()function

Pass the length of the vector as an argument to the integer() function. For example, let’s create a vector of four zeros.

# create a vector of zeros
vec <- integer(4)
# display the vector
print(vec)

Output:

[1] 0 0 0 0

You can see that we pass 4 as an argument to the integer() function. We get a vector of four zeros. Note that, here, the resulting data type of values is integer and not numeric (that we get in the other methods).

Using the numeric() function

You can similarly use the numeric() function to create a vector of zeros. It also takes the length of the vector you want to create as an argument. Let’s look at an example.

# create a vector of zeros
vec <- numeric(4)
# display the vector
print(vec)

Output:

[1] 0 0 0 0

We get the same result as above.

Using the rep() function

The rep() function is used to replicate a value a specified number of times.

To create a vector of zeros using the rep() function, pass 0 as the first argument and the vector length as the second argument. For example, let’s use the rep() function to create a vector of four zeros.

# create a vector of zeros
vec <- rep(0, 4)
# display the vector
print(vec)

Output:

[1] 0 0 0 0

We get the same result as above.
