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{stat}{The statistical transformation to use on the data for this |
|||
layer, as a string.} |

|||
a call to a position adjustment function.} |

\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. |
