Basic Graphs
One of the main reasons data analysts turn to R is for its strong graphic capabilities.
Creating a Graph provides an overivew of creating and saving graphs in R.
The remainder of the section describes how to create basic graph types. These include density plots (histograms and kernal density plots), dot plots, bar charts (simple, stacked, grouped), line charts, pie charts (simple, annotated, 3D), boxplots (simple, notched, violin plots, bagplots) and scatter plots (simple, with fit lines, scatterplot matrices, high density plots, and 3D plots).
The Advanced Graphs section describes how to customize and annotate graphs, and covers more statistically complex types of graphs.
