Given a named vector or a data frame, 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. You can perform appropriate value transformation ahead of time to get the desired waffle layout/effect.

waffle(parts, rows = 10, keep = TRUE, xlab = NULL, title = NULL,
  colors = NA, size = 2, flip = FALSE, reverse = FALSE,
  equal = TRUE, pad = 0, use_glyph = FALSE, glyph_size = 12,
  glyph_font = "Font Awesome 5 Free Solid",
  glyph_font_family = "FontAwesome5Free-Solid", legend_pos = "right")



named vector of values or a data frame to use for the chart


number of rows of blocks


keep factor levels (i.e. for consistent legends across waffle plots)


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


chart title


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


width of the separator between blocks (defaults to 2)


flips x & y axes


reverses the order of the data


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)


how many blocks to right-pad the grid with


use specified glyph; if using built-in Font Awesome, can be the glyph name; otherwise, it must be the unicode glyph from the custom font the caller is using.


size of the Font Awesome font

glyph_font, glyph_font_family

if use_glyph is not FALSE, the gplyph_font will be looked up in the font database and the glpyph_font_family used as the family parameter to ggplot for font display since fonts in R, Python and anythign that relies on legacy font C libraries are woefully messed up. You may need to adjust either of these "font" parameters depending on your system & OS version due to the fact that font names are different even between OS versions (sometimes).

The package comes with Font Awesome and helpers for it. Use of any other fonts requires the caller to be familiar with using fonts in R. NOT ALL FONTS will work with ggplot2 and definitely not under all graphics devices for ggplot2.


position of legend


If a data frame is used, the first two columns should contain the desired names and the values, respectively.

If the vector is not named or only partially named, capital letters will be used instead.

It is highly suggested that you limit the number of elements to plot, just like you should if you ever got wasted and decided that a regular pie chart was a good thing to create and then decide to be totally evil and make one to pollute this beautiful world of ours.

Chart title and x-axis labels are optional, especially if you'll just be exporting to another program for use/display.

If you specify a string (vs FALSE) to use_glyph the function will map the input to a Font Awesome glyph name and use that glyph for the tile instead of a block (making it more like an isotype pictogram than a waffle chart). You'll need to install Font Awesome 5 and use the extrafont package to be able to use Font Awesome 5 glyphs. Sizing is also up to the user since fonts do not automatically scale with graphic resize.

Glyph idea inspired by Ruben C. Arslan (@_r_c_a)


You MUST use the Font Awesome 5 fonts bundled with the package. See install_fa_fonts().
