Sankey / ribbon diagrams

Sankey diagrams are a type of flow diagrams, in which the width of the arrows is proportional to the quantity they illustrate. Riverplot allows the creation, in R, of a basic type of Sankey diagrams.

First, you need to create a specific riverplot object that can be directly plotted. (Use riverplot.example to generate an example object).

The simplest way is to create a graph-like representation of you diagram as a list of nodes; each item in the list is a list of partner nodes. Furthermore, you need to know at which position (from left to right) each node resides. Please take a look at the example section in the makeRiver function.

Once you have created a riverplot object with one of the above methods (or manually), you can plot it either with plot(x) or riverplot(x) (see riverplot for details).

Simple example from riverplot.example function: plot( riverplot.example() ).
