How to check if a Specific Item is present in the Vector in R - Step by Step Examples

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

To check if a specific item is present in a vector in R, you can use the %in% operator or the match() function.

In this example,

We have a numeric vector named num_vec.
We use the %in% operator to check if the specified item is present in the vector.
We print the result to standard output.

num_vec <- c(1, 2, 3, 4, 5)
item <- 3
result <- item %in% num_vec
print(result)

[1] TRUE

In this example,

We have a character vector named char_vec.
We use the match() function to check if the specified item is present in the vector.
We print the result to standard output.

char_vec <- c("apple", "banana", "cherry", "date")
item <- "banana"
result <- match(item, char_vec, nomatch = 0) > 0
print(result)

[1] TRUE

In this tutorial, we learned How to check if a Specific Item is present in the Vector in R language with well detailed examples.
