This chapter provides the most basic information to get started pro-ducing plots in R. First of all, there is a three-line code example that demonstrates the fundamental steps involved in producing a plot. This is followed by a series of gures to demonstrate the range of images that R can produce.
Session 4: ggplot2. Most powerful approach to statistical graphs, based on the “Grammar of Graphics”. A graphics language, composed of layers, “geoms” (points, lines, regions), each with graphical “aesthetics” (color, size, shape) part of a workflow for “tidy” data manipulation and graphics.
ggplot2 is based on the grammar of graphics, the idea that you can build every graph from the same components: a data set, a coordinate system, and b geoms—visual marks that represent data points. Basics. GRAPHICAL PRIMITIVES. a + geom_blank() and a + expand_limits() Ensure limits include values across all plots.
Lines graph, also known as line charts or line plots, display ordered data points connected with straight segments. In this tutorial you will learn how to plot line graphs in base R using the plot, lines, matplot, matlines and curve functions and how to modify the style of the resulting plots.
Line graphs can be made with discrete (categorical) or continuous (numeric) variables on the x-axis. In the example here, the variable demand is numeric, but it could be treated as a categorical variable by converting it to a factor with factor() (Figure 4.2).
