\title{Compute and display a univariate averaged shifted histogram (polynomial kernel)}
|
|
\usage{
|
|
stat_ash(mapping = NULL, data = NULL, geom = "area", position = "stack",
|
|
ab = NULL, nbin = 50, m = 5, kopt = c(2, 2), show.legend = NA,
|
|
inherit.aes = TRUE, ...)
|
|
}
|
|
\arguments{
|
|
\item{mapping}{Set of aesthetic mappings created by \code{\link{aes}} or
|
|
\code{\link{aes_}}. If specified and \code{inherit.aes = TRUE} (the
|
|
default), is combined with the default mapping at the top level of the
|
|
plot. You only need to supply \code{mapping} if there isn't a mapping
|
|
defined for the plot.}
|
|
|
|
\item{data}{A data frame. If specified, overrides the default data frame
|
|
defined at the top level of the plot.}
|
|
|
|
\item{geom}{Use to override the default Geom}
|
|
|
|
\item{position}{Position adjustment, either as a string, or the result of
|
|
a call to a position adjustment function.}
|
|
|
|
\item{ab}{half-open interval for bins \emph{[a,b)}. If no value is specified,
|
|
the range of x is stretched by \code{5\%} at each end and used the
|
|
interval.}
|
|
|
|
\item{nbin}{number of bins desired. Default \code{50}.}
|
|
|
|
\item{m}{integer smoothing parameter; Default \code{5}.}
|
|
|
|
\item{kopt}{vector of length 2 specifying the kernel, which is proportional
|
|
to \emph{( 1 - abs(i/m)^kopt(1) )i^kopt(2)}; (2,2)=biweight (default);
|
|
(0,0)=uniform; (1,0)=triangle; (2,1)=Epanechnikov; (2,3)=triweight.}
|
|
|
|
\item{show.legend}{logical. Should this layer be included in the legends?
|
|
\code{NA}, the default, includes if any aesthetics are mapped.
|
|
\code{FALSE} never includes, and \code{TRUE} always includes.}
|
|
|
|
\item{inherit.aes}{If \code{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. \code{\link{borders}}.}
|
|
|
|
\item{...}{other arguments passed on to \code{\link{layer}}. There are
|
|
three types of arguments you can use here:
|
|
|
|
\itemize{
|
|
\item Aesthetics: to set an aesthetic to a fixed value, like
|
|
\code{color = "red"} or \code{size = 3}.
|
|
\item Other arguments to the layer, for example you override the
|
|
default \code{stat} associated with the layer.
|
|
\item Other arguments passed on to the stat.

\section{Aesthetics}{

\code{geom_ash} understands the following aesthetics (required aesthetics

are in bold):

|
\item \code{alpha}
|
|
\item \code{color}
|
|
\item \code{fill}
|
|
\item \code{linetype}

\item \code{size}
