Honestly I'd focus on using it a couple times and the syntax should feel very natural afterwards. Understanding what the `aes` command is doing is the most important: it's mapping a set of features to the plot, and then you are adding various `geom` objects that visualize those features. There is a book: http://ggplot2.org/book/ http://ggplot2.org/book/ if you want to get more into the nitty gritty.
