to_alluvia

data

Numeric or character; the fields corresponding to the
axis (variable), stratum (value), and alluvium (identifying) variables.

key, value, id

Take a data frame with axis and axis value variables to be used in an 
alluvial diagram, and reshape the data frame so that the axes constitute 
separate variables whose values are given by the value variable. This 
function invokes <code><a rd-options="tidyr" href="/link/spread_?package=ggalluvial&version=0.5.0&to=tidyr" data-mini-rdoc="tidyr::spread_">spread_</a></code>.

Alluvial diagrams encompass a variety of charts that use x-splines
(alluvia and flows), sometimes augmented with stacked bars (lodes or
strata), to visualize incidence structures derived from several data types,
including repeated categorical measures, evolving classifications, and
multi-dimensional categorical data. This package contains stat and geom
layers that interpret multiple data formats compatible with this framework
while hewing to the principles of tidy data and the grammar of graphics.

to_alluvia function

Take a data frame with axis and axis value variables to be used in an 
alluvial diagram, and reshape the data frame so that the axes constitute 
separate variables whose values are given by the value variable. This 
function invokes <code><a rd-options='tidyr' href='spread_'>spread_</a></code>.
