How to check if a Specific Item is present in the Set in R ?

Answer

To check if a specific item is present in a Set in R, you can use the %in% operator.

✐ Examples

1 Check if Item is Present

In this example,

We define a vector named mySet containing elements of a specific type.
We use the %in% operator to check if a specific item is present in the vector.
The %in% operator returns TRUE if the item is present in the vector, otherwise it returns FALSE.
Finally, we print the result to standard output.

R Program

# Define vector with items
mySet <- c("apple", "banana", "orange", "grape", "melon")

# Check if item is present
item <- "banana"
isPresent <- item %in% mySet

# Print result
print(paste("Is", item, "present in the Set?", isPresent))

Output

[1] "Is banana present in the Set? TRUE"

2 Check if Item is Not Present

In this example,

We define a vector named mySet containing elements of a specific type.
We use the %in% operator to check if a specific item is not present in the vector.
The %in% operator returns FALSE if the item is not present in the vector.
Finally, we print the result to standard output.

R Program

# Define vector with items
mySet <- c("apple", "banana", "orange", "grape", "melon")

# Check if item is not present
item <- "peach"
isNotPresent <- !(item %in% mySet)

# Print result
print(paste("Is", item, "not present in the Set?", isNotPresent))

Output

[1] "Is peach not present in the Set? TRUE"
