\title{Count number of observation in rectangular bins.}
\usage{
stat_bin2d(mapping = NULL, data = NULL, geom = NULL,
position = "identity", bins = 30, drop = TRUE, ...)
}
\arguments{
\item{bins}{numeric vector giving number of bins in both vertical and
horizontal directions. Set to 30 by default.}
\item{drop}{if \code{TRUE} removes all cells with 0 counts.}
\item{mapping}{The aesthetic mapping, usually constructed with
\code{\link{aes}} or \code{\link{aes_string}}. Only needs to be set
at the layer level if you are overriding the plot defaults.}
\item{data}{A layer specific dataset - only needed if you want to override
the plot defaults.}
\item{geom}{The geometric object to use display the data}
\item{position}{The position adjustment to use for overlappling points
on this layer}
\item{...}{other arguments passed on to \code{\link{layer}}. This can
include aesthetics whose values you want to set, not map. See
\code{\link{layer}} for more details.}

\examples{
\donttest{
d <- ggplot(diamonds, aes(carat, price))
d + stat_bin2d()
d + geom_bin2d()
# You can control the size of the bins by specifying the number of
# bins in each direction:
d + stat_bin2d(bins = 10)
d + stat_bin2d(bins = 30)
# Or by specifying the width of the bins
d + stat_bin2d(binwidth = c(1, 1000))
d + stat_bin2d(binwidth = c(.1, 500))
# Or with a list of breaks
x <- seq(min(diamonds$carat), max(diamonds$carat), by = 0.1)
y <- seq(min(diamonds$price), max(diamonds$price), length = 50)
d + stat_bin2d(breaks = list(x = x, y = y))
# With qplot
qplot(x, y, data = diamonds, geom="bin2d",
xlim = c(4, 10), ylim = c(4, 10))
qplot(x, y, data = diamonds, geom="bin2d", binwidth = c(0.1, 0.1),
xlim = c(4, 10), ylim = c(4, 10))
