How to create a Set of integers in R


How to create a Set of integers in R ?

Answer

To create a set of integers in R, you can use the unique() function on a vector of integers.



✐ Examples

1 Create Set of Integers using unique() Function

In this example,

  1. We define a vector named number_vector containing integers.
  2. We apply the unique() function to the vector to remove duplicates and create a set.
  3. The resulting set contains unique integers without duplicates.

R Program

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

# Create a set of integers using unique() function
number_set <- unique(number_vector)

# Print the set
print(number_set)

Output

[1] 1 2 3 4 5

2 Create Set of Integers using sets Package

In this example,

  1. We install and load the sets package if it's not already installed.
  2. We define a vector named number_vector containing integers.
  3. We use the set() function from the sets package to create a set from the vector.
  4. The resulting set contains unique integers without duplicates.

R Program

# Install and load the sets package if not already installed
if (!requireNamespace("sets", quietly = TRUE)) {
  install.packages("sets")
}
library(sets)

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

# Create a set of integers using set() function
number_set <- set(number_vector)

# Print the set
print(number_set)

Output

[1] 1 2 3 4 5
