qplot_waffle(x, shape = 15, rows = NULL, cols = NULL,
  drop_shadow_h = -0.3, drop_shadow_v = 0.3)

Arguments

x	a variable with not too many unique values
shape	defaults to a filled square
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
