# Selection by comparison I

Sometimes you want to select elements from a vector in a more advanced fashion. This is where the use of logical operators may come in handy.

The (logical) comparison operators known to R are:
- `<`

for less than
- `>`

for greater than
- `<=`

for less than or equal to
- `>=`

for greater than or equal to
- `==`

for equal to each other
- `!=`

not equal to each other

The nice thing about R is that you can use these comparison operators on vectors. For example, the statement c(4,5,6) > 5 returns: FALSE FALSE TRUE. In other words, you test for every element of the vector if the condition stated by the comparison operator is TRUE or FALSE.

Behind the scenes, R does an element-wise comparison of each element in the vector c(4,5,6) with the element 5. However, 5 is not a vector of length three. To solve this, R automatically replicates the value 5 to generate a vector of three elements, c(5, 5, 5) and then carries out the element-wise comparison.

- Check which values in
`numeric_vector`

are larger than 10. Assign the result to the variable`larger_than_ten`

. - print the variable
`larger_than_ten`

to the console.
