If you attempt to run code with the plus sign at the beginning of a line, preceding geom_point(), as in the previous example, a blank plot, as shown in the preceding screenshot, will generate in your Plots window in RStudio and you will get the following error in your console:

Error in +geom_point() : invalid argument to unary operator

Let's walk through some basic types of ggplots using the mtcars dataset, which we've used a few times so far and will continue to use throughout the book. Built-in datasets in R are convenient to use for trying to learn new things; plus they can be helpful to use for creating examples for others when we need help with something.
