Lesson 11 - Plotting

What you will learn in this lesson:

• What is ggplot2.
• How to make plots.
• How to filter data.
• How layers work in ggplot2.
• How to customize plots.
• How to use RStudio to find errors.
• How to apply themes to plots.

We saw in lesson 4 that base R has workable plotting capabilities. But base plots are not that great.

Luckily for us, the Tidyverse comes with a terrific plotting library: ggplot2ggplot2 is probably one of the most, if not the most, consequential library in R.

ggplot2 is a powerhouse and can feel intimidating. In my opinion, ggplot2 is like everything else: much less intimidating once we understand how it works.
