Graphing in R will be crucial in your data science work, and we have covered most of the basics here. However, graphing is one of those things where, most of the time, there are always going to be different types of graphs you haven't heard of yet and options you haven't yet selected, so it's important to know where to look for assistance and how to keep learning.
