Creating Boxplots using ggplot2

Let us create a boxplot using geom_boxplot().

1. Create a boxplot of sleep_total with vore, both variables from the msleep dataset using the following code:

Notice that omni seems to have four outliers, represented by the black dots outside of the boxes, which represent the Interquartile Range (IQR) of the sleep_total of each variable. 

ggplot(msleep, aes(vore, sleep_total)) + geom_boxplot()

Output: We get the following boxplot as the output after executing the preceding code:

While these four types of plots are far from everything available in ggplot2, everything we've gone over so far in this subtopic should ...
