Check if any value in an R vector is greater than or less than a certain value.

To check if any value in an R vector is greater than or less than a certain value, we can use any function.

For Example, if we have a vector called V and we want to check if any value in V is greater than 100 then we can use the command given below −

any(V>100)

Similarly, we can check if any value is less than 100 by using the command as follows −

any(V<100)

Check out the below Examples to understand how it works,
