This dataset is shipped with the ggplot2 package in the tidyverse in R. If you haven’t already installed the tidyverse package, go ahead and do so. You only need to do this one time in RStudio. Thereafter, just load the library. It contains measurements on 10 different variables (like price, color, clarity, etc.) for 53,940 different diamonds.
In RStudio, you can load the dataset with the commands library(ggplot2) and library(diamonds) followed by data(diamonds). The diamonds dataset has 53,930 rows.
In RStudio you can get Help on the dataset with the command ?diamonds. As the most popular diamond shape, the Round Cut Diamond represents a large majority of all diamonds sold. In fact, data from diamond vendors suggests that around two thirds of consumers opt for the round cut when choosing a diamond. They’re cut with 58 facets that all reflect light back to your eyes.
This is what you will see in the console of RStudio.

Let’s use the str() function. This is the structure function.
