Description
We describe the features and implementation of the R package zenplots (zigzag expanded navigation plots) for displaying high-dimensional data according to the recently
proposed zenplots.
By default, zenplots lay out alternating one- and two-dimensional plots in a zigzag-like
pattern where adjacent axes share the same variate. Zenplots are especially useful when
subsets of pairs can be identified as of particular interest by some measure, or as not
meaningfully comparable, or when pairs of variates can be ordered in terms of potential
interest to view, or the number of pairs is too large for more traditional layouts such as
a scatterplot matrix. They also allow an essentially arbitrary layout of plots. A highdimensional space can be explored in a zenplot (zenplot()) by navigating through lower
dimensional subspaces along a zenpath (zenpath()) which orders the dimensions (i.e.,
variates) visited according to some measure of interestingness; see Hofert and Oldford
(2018) for an application to S&P 500 constituent data.
The R package zenplots provides compact displays for high-dimensional data via the
notion of zenplots, grouping of variates, and customizable displays of zigzag layouts. It
accommodates different graphical systems including the base graphics package of R Core
Team (2020b), the package grid of R Core Team (2020a) (and hence packages like ggplot2
of Wickham et al. 2020), and the interactive graphical package loon of Waddell and
Oldford (2020). zenplots handles groups of variates, partial and fully missing data, and
more. One important feature is that zenplot() and its auxiliary functions in zenplots
distinguish layout from plotting which allows one to freely choose and create one- and twodimensional plot functions; predefined functions are exported for all graphical systems.
All R plots in this paper are reproducible with the vignette "selected_features"
(available in zenplots ≥ 0.0-2).
