Divides the plane into rectangles, counts the number of cases in
each rectangle, and then (by default) maps the number of cases to the
rectangle's fill. This is a useful alternative to
in the presence of overplotting.

Set of aesthetic mappings created by

inherit.aes = TRUE (the

plot. You must supply
mapping if there is no plot mapping.

often aesthetics, used to set an aesthetic to a fixed value, like

NA, the default, includes if any aesthetics are mapped.
FALSE never includes, and
TRUE always includes.
FALSE, overrides the default aesthetics,
rather than combining with them. This is most useful for helper functions
that define both data and aesthetics and shouldn't inherit behaviour from
the default plot specification, e.g.

Numeric vector giving bin width in both vertical and

bins if both set.
TRUE removes all cells with 0 counts.
stat_bin2d understands the following aesthetics (required aesthetics are in bold):
