Chapter 17 Diagrams

It is often useful to express analysis using flowcharts and diagrams within reports. Although there are many separate programs which can be used to produce these, it can be beneficial to create these within our analysis directly. This makes it easier to update and edit the graph if we need to edit it in the future, and allows us to use the results from our analysis directly within the diagrams, making them more information.

While there are several different packages available for R, we will focus on the package DiagrammeR (Iannone 2020). We also recommend that you read at http://rich-iannone.github.io/DiagrammeR/index.html . In this chapter we will explain some of the basic usages of the package.
