\alias{stat_ecdf}
\title{Empirical Cumulative Density Function}
\usage{
stat_ecdf(mapping = NULL, data = NULL, geom = "step",
position = "identity", n = NULL, ...)
}
\arguments{
\item{n}{if NULL, do not interpolate. If not NULL, this is the number
of points to interpolate with.}
\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.}
}
\value{
a data.frame with additional columns:
\item{x}{x in data}
\item{y}{cumulative density corresponding x}
}
\description{
Empirical Cumulative Density Function
}
\examples{
\donttest{
qplot(rnorm(1000), stat = "ecdf", geom = "step")
df <- data.frame(x = c(rnorm(100, 0, 3), rnorm(100, 0, 10)),
g = gl(2, 100))
ggplot(df, aes(x, colour = g)) + stat_ecdf()
