In the previous lesson, we imported three files stored in three different variables:
roads_raw. To continue our work, we need to merge them into a single data frame. Let’s call this unified data frame
dep_all. To merge the data frames, we need to structure all three similarly. We will prepare each variable first, and then we will do the merging.
One aspect where the Tidyverse shines is when it comes to importing and preparing data. Almost all the functions we will use in this lesson come from the Tidyverse.
