How to check if a Set is Not Empty in R ?

Answer

In R, you can use the length() function to check if a Set is not empty.

✐ Examples

1 Check if Set is Not Empty

In this example,

We declare a Set named set and initialize it with some elements.
We use the length() function on the Set set to determine its length.
If the length of the Set is greater than 0, it means the Set is not empty; otherwise, it is empty.
We print the result to the standard output to indicate whether the Set is not empty or not.

R Program

# Initialize a Set
set <- c(1, 2, 3) # Or set <- numeric(0) for an empty Set

# Check if Set is not empty
if (length(set) > 0) {
  print('The Set is not empty')
} else {
  print('The Set is empty')
}

Output

The Set is not empty

2 Check if Empty Set is Not Empty

In this example,

We declare an empty Set named emptySet.
We use the length() function on the Set emptySet to determine its length.
Since the length of the Set is 0, it means the Set is empty.
We print the result to the standard output to indicate that the Set is indeed empty.

R Program

# Initialize an empty Set
emptySet <- numeric(0)

# Check if Empty Set is not empty
if (length(emptySet) > 0) {
  print('The Set is not empty')
} else {
  print('The Set is empty')
}

Output

The Set is empty
