Waffleplot: Make waffle (square pie) charts

Description

Given a named vector, this function will return a ggplot object that represents a waffle chart of the values. The individual values will be summed up and each that will be the total number of squares in the grid.

Usage

Waffleplot(parts, rows = 10, xlab = NULL, title = NULL, colors = NA, size = 2, legend_pos = "right", flip = FALSE, reverse = FALSE, equal = TRUE, pad = 0, use_glyph = FALSE, glyph_size = 12)

Arguments

parts

named vector of values to use for the chart

rows

number of rows of blocks

xlab

text for below the chart. Highly suggested this be used to give the "1 sq == xyz" relationship if it's not obvious

title

chart title

colors

exactly the number of colors as values in parts. If omitted, Color Brewer "Set2" colors are used.

size

width of the separator between blocks (defaults to 2)

legend_pos

position of legend

flip

flips x & y axes

reverse

reverses the order of the data

equal

by default, waffle uses coord_equal; this can cause layout problems, so you an use this to disable it if you are using ggsave or knitr to control output sizes (or manually sizing the chart)

pad

how many blocks to right-pad the grid with

use_glyph

use specified FontAwesome glyph

glyph_size

size of the FontAwesome font

Examples

tiles <- c(One=80, Two=30, Three=20, Four=10)
Waffleplot(tiles, rows=8)

Senate <- c(`Male (44%)`=44, `Female (56%)`=56)
Waffleplot(Senate, rows=10, size=0.5, colors=c("#af9139", "#544616"))
