Selection by comparison $-$ Step $1$

By making use of comparison operators, we can approach the previous question in a more proactive way.

The $($logical$)$ comparison operators known to $R$ are:

for less than

$>$ for greater than

for less than or equal to

$==$ for equal to each other

$$ not equal to each other

As seen in the previous chapter, stating $6>5$ returns TRUE. The nice thing about $R$ is that you can use these comparison operators also on vectors. For example:

$c(4,5,6)>5$

$[1]$ FALSE FALSE TRUE

This command tests for every element of the vector if the condition stated by the comparison operator is TRUE or FALSE $.$
