How do you create a histogram using ggplot2?
- If we want to create a histogram with the ggplot2 package, we need to use the geom_histogram function. The R code of Example 1 shows how to draw a basic ggplot2 histogram. Figure 1 visualizes the output of the previous R syntax: A histogram in the typical design of the ggplot2 package.
What are the advantages of using ggplot2 to create a histogram?
- If you need to create a histogram in R, I strongly recommend that you use ggplot2 instead. ggplot2 is a powerful plotting library that gives you great control over the look and layout of the plot. The syntax is easier to modify, and the default plots are fairly beautiful.
What is the default binwidth for a ggplot2 histogram?
- Ggplot2 tells us that the “bins” attribute was given the default value of 30. It also tells us that we can pick a better value using the “binwidth” attribute. What are bins? you may be asking. Well, as previously alluded to, they refer to the subranges a histogram produces of the variable being plotted.
