Summary
In this chapter, we covered the basic syntax and techniques to produce graphs in R. We covered the essential details for creating scatterplots and line plots, and discussed a range of syntax and techniques that are useful for other kinds of graph. I hope that you found this chapter a useful start on graphing in R.
In the next chapter, we will cover a range of topics that you will need if you want to create professional-level graphs for your own research and analysis. It contains very useful material, so please continue to work through this book by making a start on the next chapter as quickly as possible. For example, in this chapter, though we saw how to draw a regression line, in the next chapter we will go a little further on the topic of graphing regression lines. However, the further chapters have many other interesting techniques for you to learn.
