\title{Points, jittered to reduce overplotting.}
\usage{
geom_jitter(mapping = NULL, data = NULL, stat = "identity",
  position = "jitter", na.rm = FALSE, ...)
}
\arguments{
\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{stat}{The statistical transformation to use on the data for this
layer.}

\item{position}{The position adjustment to use for overlapping points
on this layer}

\item{na.rm}{If \code{FALSE} (the default), removes missing values with
a warning.  If \code{TRUE} silently removes missing values.}

\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.}
}
\description{
The jitter geom is a convenient default for geom_point with position =
'jitter'.  See \code{\link{position_jitter}} to see how to adjust amount
of jittering.

\examples{
p <- ggplot(mpg, aes(displ, hwy))
p + geom_point()
p + geom_point(position = "jitter")

# Add aesthetic mappings
p + geom_jitter(aes(colour = cyl))

# Vary parameters
p + geom_jitter(position = position_jitter(width = .5))
p + geom_jitter(position = position_jitter(height = .5))

# Use qplot instead
qplot(displ, hwy, data = mpg, geom = "jitter")
qplot(class, hwy, data = mpg, geom = "jitter")
qplot(class, hwy, data = mpg, geom = c("boxplot", "jitter"))
qplot(class, hwy, data = mpg, geom = c("jitter", "boxplot"))
