The use of the if…else conditional operator

The general structure of an if…else statement is as follows:

    if (conditional_expression) {
       body_of_task
    } else {
       body_of_task2  
    }

The general structure is clearly intuitive to understand. If the conditional expression produces a result that is TRUE, then it will execute the body_of_task section, and if the conditional expression is FALSE, then it will execute the body_of_task2 section. In this recipe, you will implement a small task to implement the if…else statement.

Getting ready

Unlike the ifelse function, if…else works for conditioning on a scalar-valued input and output. The ifelse function takes the input as a vector and produces...
