 But copy-pasting is error prone. So there are two alternatives; I either write a function that
 takes as argument the data and the `id` I want to plot and run it for each `id` (we will learn to

+We are going to learn about this in detail in Chapter 8. Let's go through each line.
+In the first line, I have started from my clean data `nested_survey_data` and then, using `%>%`
 and `mutate()` I create a new column called `plot`. Inside the `mutate()` function, I called `map2`.
 `map2` is a `{purrr}` function that takes three inputs: `.x`, `.y` and a function. `.x` is the `id`
 column from my data, and `.y` is the `data` column from `nested_survey_data`. The function is the
 ggplot I created before. Think of `map2()` has a loop over two lists, all while applying a function.

 Functional programming is a paradigm that I find very suitable for data science. In functional
 programming, your code is organised into functions that perform the operations you need. Your scripts
