What are vectors?
Vector operations
Indexing and filtering
Simple analysis
Summary

Instruction

Perfect! One last thing we'd like to mention is that you can pass a filtered vector directly to a function as its argument without having to store that filtered vector in a separate variable.

For example, if we would like to calculate the average of the ages that are less than 35 in our vector named ages, we can do the following:

mean(ages[ages < 35])

R will first perform the appropriate vector filtering and afterwards apply the mean function.

Exercise
