Using Different Bar Chart Aesthetic Options

Let's now create bar charts using the dodge and fill bar chart position aesthetic options.

1. If not loaded from the last topic, load the msleep dataset using data("msleep").

2. Create a bar chart using the dodge position aesthetic of vore, filled with the conservation variable. (These variables are already declared as factor variables when you load msleep.) The code for this is as follows:

ggplot(msleep, aes(vore, fill = conservation)) + geom_bar(position = "dodge")

3. Create a bar chart with the same variables, this time using the fill position aesthetic:

ggplot(msleep, aes(vore, fill = conservation)) + geom_bar(position = "fill")

Output: The following is the output we get when we execute the code ...
