Getting ready

To implement this recipe, you only need a single numeric variable and a cut-off value to execute the conditional statement. Let’s say you have the following variable with the values representing the number of hours spent on social media in a week:

    x <- c(13, 21, 19, 18, 21, 16, 21, 24, 17, 18, 12, 18, 29, 17, 18,        11, 13, 20, 25, 18, 15, 19, 21, 21, 7, 12, 23, 31, 16, 19, 23, 15,    25, 19, 15, 25, 25, 16, 29, 15, 26, 29, 23, 24, 20, 19, 14, 27,    22, 26)

The cut-off value is the median of the given variable. The objective is to create a new variable as follows: The value of the new variable is 1 if the value of given variable is greater than median; otherwise, it is 0. Before writing the code for the recipe, you must understand ...
