All about aesthetics: color, shape and size
In the video you saw 9 visible aesthetics. Let's apply them to a categorical variable — the cylinders in mtcars, cyl.
These are the aesthetics you can consider within aes() in this chapter: x, y, color, fill, size, alpha, labels and shape.
One common convention is that you don't name the x and y arguments to aes(), since they almost always come first, but you do name other arguments.
In the following exercise the fcyl column is categorical. It is cyl transformed into a factor.
