In grebbel/formr_test: formr survey framework

Description

Pass in a a variable and get a waffle plot. Useful to display simple counts or if the variable has different values, a square pie chart. If the variable has a length that makes the individual squares hard to see, consider showing hundreds, thousands etc.

Usage

qplot_waffle_text(x, symbol = fontawesome_square, rows = NULL,
  cols = NULL, drop_shadow_h = -0.9, drop_shadow_v = 0.9,
  font_family = "FontAwesome", font_face = "Regular",
  font_size = round(140/sqrt(length(x))))

Arguments

x	a variable with not too many unique values
symbol	pass a unicode symbol from FontAwesome here. Defaults to a square with rounded edges
rows	defaults to the rounded up square root of the number of values
cols	defaults to the rounded down square root of the number of values
drop_shadow_h	horizontal offset of the drop shadow, tinker with this to get a proper shadow effect
drop_shadow_v	vertical offset of the drop shadow
font_family	defaults to FontAwesome
font_face	defaults to Regular
font_size	defaults to round(140/sqrt(length(x)))

Details

This functions is like waffle_plot but it allows you to specify custom symbols from FontAwesome. Copypaste them from here: http://fontawesome.io/cheatsheet
