vtree is a flexible tool for generating variable trees —
diagrams that display information about nested subsets of a data frame.
Given simple specifications,
the vtree
function produces these diagrams and automatically
labels them with counts, percentages, and other summaries.
With vtree, you can:
explore a data set interactively, and
produce customized figures for reports and publications.
For a comprehensive introduction see the vignette.
