The group by verb allows data to be categorized into a hierarchy of groups. For instance, data could be grouped by continent, country, and then city. Dplyr operations like filtering, sampling, or calculating values using mutate can be done within these groups.

But I thoroughly recommend you understand the relationship between tibbles and data frames if you're going to be a hardcore user of group by and dplyr. Let's look at some examples of using group by inside of our studio. So, inside of our project, we have a file called data dash processing, which is where we'll be working. So let's open that up. And at the top of the file, we load the tidyverse, so we'll run that code with command…
