How to create a Vector of Size N in R - Step by Step Examples

How to create a Vector of Size N in R ?

Answer

To create a vector of size N in R, you can use functions like numeric(), integer(), character(), or logical(), which create vectors of specified lengths filled with default values.

✐ Examples

1 Create a Numeric Vector of Size N

In this example,

We use the numeric() function to create a numeric vector. This function takes a single argument, n, which specifies the size of the vector.
The numeric() function initializes a vector of length n with all elements set to 0.
We assign the resulting vector to a variable named num_vector.
Finally, we print the vector using the print() function to display its contents.

R Program

n <- 5
num_vector <- numeric(n)
print(num_vector)

Output

[1] 0 0 0 0 0

2 Create an Integer Vector of Size N

In this example,

We use the integer() function to create an integer vector. This function takes a single argument, n, which specifies the size of the vector.
The integer() function initializes a vector of length n with all elements set to 0.
We assign the resulting vector to a variable named int_vector.
Finally, we print the vector using the print() function to display its contents.

R Program

n <- 5
int_vector <- integer(n)
print(int_vector)

Output

[1] 0 0 0 0 0

3 Create a Character Vector of Size N

In this example,

We use the character() function to create a character vector. This function takes a single argument, n, which specifies the size of the vector.
The character() function initializes a vector of length n with all elements set to an empty string "".
We assign the resulting vector to a variable named char_vector.
Finally, we print the vector using the print() function to display its contents.

R Program

n <- 5
char_vector <- character(n)
print(char_vector)

Output

[1] "" "" "" "" ""

4 Create a Logical Vector of Size N

In this example,

We use the logical() function to create a logical vector. This function takes a single argument, n, which specifies the size of the vector.
The logical() function initializes a vector of length n with all elements set to FALSE.
We assign the resulting vector to a variable named log_vector.
Finally, we print the vector using the print() function to display its contents.

R Program

n <- 5
log_vector <- logical(n)
print(log_vector)

Output

[1] FALSE FALSE FALSE FALSE FALSE
