How to check if a Specific Element is present in the List in R ?

Answer

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

✐ Examples

1 Check Element Presence in List (Integer)

In this example,

We create a list named my_list with some elements.
We use the %in% operator to check if the specified element is present in the list.
The %in% operator returns TRUE if the element is present, otherwise FALSE.
Finally, we print the result to standard output.

R Program

my_list <- c(10, 20, 30, 40, 50)
search_element <- 40
is_present <- search_element %in% my_list
print(paste('Element presence in list:', is_present))

Output

Element presence in list: TRUE

2 Check Element Presence in List (String)

In this example,

We create a list named my_list with some string elements.
We use the %in% operator to check if the specified string is present in the list.
The %in% operator returns TRUE if the string is present, otherwise FALSE.
Finally, we print the result to standard output.

R Program

my_list <- c('apple', 'banana', 'cherry', 'date', 'elderberry')
search_element <- 'cherry'
is_present <- search_element %in% my_list
print(paste('Element presence in list:', is_present))

Output

Element presence in list: TRUE
