plot_condensation

plotting the condensation potential is meant as a decision aid
 for which variables to include in an alluvial plot. All variables are
 transformed to categoric variables and then two variables are selected by
 which the dataframe will be grouped and summarized by. The pair that
 results in the greatest condensation of the original dataframe is selected.
 Then the next variable which offers the greatest condensation potential is
 chosen until all variables have been added. The condensation in percent is
 then plotted for each step along with the number of groups (flows) in the
 dataframe. By experience it is not advisable to have more than 1500 flows
 because then the alluvial plot will take a long time to render. If there is
 a particular variable of interest in the dataframe this variable can be
 chosen as a starting variable.

Alluvial plots are similar to sankey diagrams and visualise categorical data
over multiple dimensions as flows. (Rosvall M, Bergstrom CT (2010) Mapping Change in
Large Networks. PLoS ONE 5(1): e8694. <doi:10.1371/journal.pone.0008694>
Their graphical grammar however is a bit more complex then that of a regular x/y
plots. The 'ggalluvial' package made a great job of translating that grammar into
'ggplot2' syntax and gives you many options to tweak the appearance of an alluvial
plot, however there still remains a multi-layered complexity that makes it difficult
to use 'ggalluvial' for explorative data analysis. 'easyalluvial' provides a simple
interface to this package that allows you to produce a decent alluvial plot from any
dataframe in either long or wide format from a single line of code while also handling
continuous data. It is meant to allow a quick visualisation of entire dataframes
with a focus on different colouring options that can make alluvial plots a great
tool for data exploration.
