We can check if a vector contains a given value using the %in% operator. For this, we have to create a vector with some values. And we have to read input from the user for what value to be checked. Or we can assign some value to a variable explicitly. Using the %in% operator with the below-given syntax we can find the element we are looking for.
Syntax :
value_to_be_checked %in% vector
The above operation only returns a boolean value that is true or false.
Steps –
- Create vector
- Set value to be searched
- Using the given syntax, search for the element in the vector
- If found print true
- Else false
Example 1 :
R
vec1 = c(1,2,3,4,5)
a = 1
a %in% vec1
|
Output :
TRUE
Example 2 :
R
vec1 = c("karthik", "nikhil", "sravan")
a = "karthik"
a %in% vec1
|
Output :
TRUE
Example 3 :
R
vec1 = c("karthik", "nikhil", "sravan")
a = "krishna"
a %in% vec1
|
Output :
FALSE
