How to create an Empty Set in R ?

Answer

To create an empty set in R, you can use the set() function without passing any initial elements.

✐ Examples

1 Create Empty Set

In this example,

We use the set() function to create an empty set in R without specifying any initial elements.
This function initializes an empty set ready to store unique elements.
We can perform set operations such as adding elements, removing elements, and checking for membership on the empty set.

R Program

# Create an empty set
empty_set <- set()

# empty_set is now ready to be used as an empty set

# Example usage:
# Add elements to the set
empty_set <- union(empty_set, c(5))

# Remove elements from the set
empty_set <- setdiff(empty_set, c(5))

# Check if an element is present in the set
contains_element <- 5 %in% empty_set

print(paste('Is element 5 present in the set:', contains_element))

Output

[1] "Is element 5 present in the set: FALSE"

2 Create Empty Set using Set Literal

In this example,

We can also create an empty set in R using the empty set literal set().
This method provides a more concise way to create an empty set compared to invoking the set() function.
We can manipulate the empty set using set operations such as adding elements, removing elements, and checking for membership.

R Program

# Create an empty set using set literal
empty_set_literal <- set()

# empty_set_literal is now ready to be used as an empty set

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

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

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

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

Output

[1] "Is element 'apple' present in the set: FALSE"
