How to Initialize a Set in R - Step by Step Examples

How to Initialize a Set in R ?

Answer

To initialize a set in R, you can use the set() function with or without initial elements.


✐ Examples

1 Initialize Set with Elements

In this example,

  1. We use the set() function to create a set in R with initial elements.
  2. We pass a vector of elements to the set() function to initialize the set with these elements.
  3. This method creates a set containing the elements provided, ensuring uniqueness of elements.
  4. We can now manipulate the set using set operations such as adding elements, removing elements, and checking for membership.

R Program

# Initialize a set with elements
my_set <- set(c("apple", "banana", "orange"))

# my_set is now initialized with elements "apple", "banana", and "orange"

# Example usage:
# Add elements to the set
my_set <- union(my_set, c("kiwi"))

# Remove elements from the set
my_set <- setdiff(my_set, c("banana"))

# Check if an element is present in the set
contains_element <- "apple" %in% my_set

print(paste("Is element 'apple' present in the set:", contains_element))

Output

Is element 'apple' present in the set: TRUE

2 Initialize Empty Set

In this example,

  1. We use the set() function without passing any arguments to create an empty set in R.
  2. This creates an empty set ready to be used for storing unique elements.
  3. We can now manipulate the empty set using set operations such as adding elements, removing elements, and checking for membership.

R Program

# Initialize an empty set
empty_set <- set()

# empty_set is now initialized as an empty set

# Example usage:
# Add elements to the set
empty_set <- union(empty_set, c("apple"))

# Remove elements from the set
empty_set <- setdiff(empty_set, c("apple"))

# Check if an element is present in the set
contains_element <- "apple" %in% empty_set

print(paste("Is element 'apple' present in the set:", contains_element))

Output

Is element 'apple' present in the set: FALSE
