If we want to check whether an item exists in a given matrix or not, we use the `%in%` operator.

## Example



# creating a matrix
mymatrix <- matrix(c("apple", "banana", "cherry", "orange"), nrow = 2, ncol = 2)

# to check if banana exists in the matrix
"banana" %in% mymatrix

## Explanation
We create a 2x2 matrix (a matrix with 2 rows and 2 columns) `mymatrix`. Using the `%in%` operator, we check if the element `"banana"` exists in the matrix or not. The output of the code `TRUE`  means that the element can be found in the given matrix.
