Mosaic Plots in the 'ggplot2' Framework

Mosaic plots in the 'ggplot2' framework. Mosaic plot functionality is provided in a single 'ggplot2' layer by calling the geom 'mosaic'.

ggmosaic was designed to create visualizations of categorical data and is capable of producing bar charts, stacked bar charts, mosaic plots, and double decker plots.

Installation

You can install ggmosaic from github with:

# install.packages("devtools")
devtools::install_github("haleyjeppson/ggmosaic")

Example

library(ggmosaic)
#> Loading required package: ggplot2
ggplot(data = fly) +
  geom_mosaic(aes(x = product(RudeToRecline), fill=DoYouRecline))

geom_mosaic: setting the aesthetics

Aesthetics that can be set:

  • weight : select a weighting variable
  • x : select variables to add to formula
    • declared as x = product(x1, x2, …)
  • fill : select a variable to be filled
    • if the variable is not also called in x, it will be added to the formula in the first position
  • conds : select a variable to condition on
    • declared as conds = product(cond1, cond2, …)

These values are then sent through productplots functions to create the formula for the desired distribution

Formula: weight ~ fill + x | conds

From the aesthetics to the formula

Example of how the formula is built

  • weight = 1
  • x = product(Y, X)
  • fill = W
  • conds = product(Z)

These aesthetics set up the formula for the distribution: 1 ~ W + X + Y | Z

Because a mosaic plot is constructed hierarchically through alternating spines, the ordering of the variables is very important.
