geom_errorbarh

The aesthetic mapping, usually constructed
 with <code><a href="/link/aes?package=ggplot2&version=0.9.2.1" rd-options="" data-mini-rdoc="ggplot2::aes">aes</a></code> or <code><a href="/link/aes_string?package=ggplot2&version=0.9.2.1" rd-options="" data-mini-rdoc="ggplot2::aes_string">aes_string</a></code>. Only
 needs to be set at the layer level if you are overriding
 the plot defaults.

mapping

A layer specific dataset - only needed if you
  want to override the plot defaults.

data

The statistical transformation to use on the
  data for this layer.

stat

The position adjustment to use for
  overlappling points on this layer

position

other arguments passed on to
 <code><a href="/link/layer?package=ggplot2&version=0.9.2.1" rd-options="" data-mini-rdoc="ggplot2::layer">layer</a></code>. This can include aesthetics whose
 values you want to set, not map. See <code><a href="/link/layer?package=ggplot2&version=0.9.2.1" rd-options="" data-mini-rdoc="ggplot2::layer">layer</a></code>
 for more details.

An implementation of the grammar of graphics in R. It
        combines the advantages of both base and lattice graphics:
        conditioning and shared axes are handled automatically, and you
        can still build up a plot step by step from multiple data
        sources. It also implements a sophisticated multidimensional
        conditioning system and a consistent interface to map data to
        aesthetic attributes. See the ggplot2 website for more
        information, documentation and examples.
