\alias{geom_errorbarh}
\title{Horizontal error bars}
\usage{
geom_errorbarh(mapping = NULL, data = NULL, stat = "identity",
position = "identity", ...)
}
\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{...}{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.}
