r-cran-ggalluvial - 0.12.5-2 main

Alluvial plots use variable-width ribbons and stacked bar plots to
represent multi-dimensional or repeated-measures data with categorical or
ordinal variables; see Riehmann, Hanfler, and Froehlich (2005)
and Rosvall and Bergstrom (2010)
.
Alluvial plots are statistical graphics in the sense of Wilkinson (2006)
; they share elements with Sankey diagrams and
parallel sets plots but are uniquely determined from the data and a small
set of parameters. This package extends Wickham's (2010)
layered grammar of graphics to generate
alluvial plots from tidy data.
