R Programming By Example

Communicating Sales with Visualizations

In this chapter, we will explore a very important and useful aspect of data analysis, data visualization. We will show how to create graph functions, which are the functions that encapsulate the process of creating a graph and output a graph object that can be seen or saved to disk. Working with graphs this way increases efficiency, adds flexibility, and provides repeatable processes.

The types of graphs we will create during this chapter include bar graphs, boxplots, scatter plots with marginal distributions, radar graphs, 3D interactive scatter plots, time-series graphs, static and interactive maps, and a cool globe visualization. The chapter will show the fundamentals you need to create a great variety ...
