How to Get Length of a Set in R - Step by Step Examples

How to Get Length of a Set in R ?

Answer

To get the length of a set in R, you can use the length function.


✐ Examples

1 Get Length of a Set with Elements

In this example,

  1. We create a set named my_set using the c function, which combines multiple elements into a vector.
  2. We convert the vector to a set using the unique function, which ensures all elements are unique.
  3. We use the length function to get the number of elements in the set.
  4. Finally, we print the length of the set using the print function.

R Program

my_set <- unique(c('apple', 'banana', 'orange'))

# Get the length of the set
length_of_set <- length(my_set)

# Print the length of the set
print(paste('Length of the set:', length_of_set))

Output

Length of the set: 3

2 Get Length of an Empty Set

In this example,

  1. We create an empty set named empty_set using the c function with no elements.
  2. We use the unique function to ensure it is treated as a set (though it will still be empty).
  3. We use the length function to get the number of elements in the set.
  4. Finally, we print the length of the set using the print function.

R Program

empty_set <- unique(c())

# Get the length of the empty set
length_of_empty_set <- length(empty_set)

# Print the length of the empty set
print(paste('Length of the empty set:', length_of_empty_set))

Output

Length of the empty set: 0
