Introduction to ggplot2. 5. Drawing graphs with ggplot2. If you need help with ggplot2, you can look at the R Graphics Cookbook. A pdf version is available online at: deca.cuc.edu.cn/Community/media/p/23508/download.aspx. Also good: www.cookbook-r.com. To draw graphs, you are going to use a package called
Introduction to ggplot2. N. Matloff. January 11, 2013. 1 Introduction. Hadley Wickham's ggplot2 package is a very popular alternative to R's base graphics package. (Others include lattice, ggobi and so on.) The ggplot2 pacakge is an implementation of the ideas in the book, The Grammar of Graphics, by Leland. Wilkison
In this chapter, you will learn to make a wide variety of plots with your first ggplot2 function, qplot(), short for quick plot. qplot makes it easy to produce complex plots, often requiring several lines of code using other plotting systems, in one line. qplot() can do this because it's based on the grammar of graphics, which allows

Description A system for 'declaratively' creating graphics, based on ``The Grammar of Graphics''. You provide the data, tell 'ggplot2' how to map variables to aesthetics, what graphical primitives to
ggplot2 is based on the grammar of graphics, the idea that you can build every graph from the same few components: a data set, a set of geoms—visual marks that represent data points, and a coordinate system. To display data values, map variables in the data set to aesthetic properties of the geom like size, color,.

head(diamonds). A dataset containing the prices and other attributes of almost 54,000 diamonds. The variables are as follows: # price = price in US dollars ($326–$18,823). # carat = weight of the diamond (0.2–5.01). # cut = quality of the cut (Fair, Good, Very Good, Premium, Ideal). # colour = diamond colour, from J (worst)
ggplot2 is an R package for producing statistical, or data, graphics, but it is unlike most other graphics packages because it has a deep underlying grammar. This grammar, based on the Grammar of Graphics (Wilkinson,. 2005), is composed of a set of independent components that can be composed in many different ways.
