StatSquareplot is ggplot2::StatBin: binwidth, bins, center,
boundary, closed, breaks and pad all mean exactly what they mean on
a histogram, because they are the histogram's own code. GeomSquareplot
re-expands each bin into one rectangle per observation. Pair the two in a
ggplot2::layer() to put countable squares in a plot you are assembling
yourself.
Format
A ggplot2::Stat object.
Details
The one difference from a plain histogram is the binwidth chosen when the
call names no grid at all: integer-valued data over a small range gets one
bin per integer, rather than stat_bin's bins = 30 default, because
thirty slivers is the wrong advice for a plot whose point is countability.
