\description{Sequential, diverging and qualitative colour scales from colorbrewer.org}
\details{
See <a href='http://colorbrewer.org'>colorbrewer.org</a> for more info
This page describes scale\_brewer, see \code{\link{layer}} and \code{\link{qplot}} for how to create a complete plot from individual components.

\usage{scale_colour_brewer(name = NULL, palette = 1, type = "qual",
na.colour = "grey80", limits = NULL, breaks = NULL, labels = NULL,
formatter = identity, legend = TRUE, ...)}
\arguments{
\item{name}{name of scale to appear in legend or on axis. Maybe be an expression: see ?plotmath}
\item{palette}{Either numeric or character. If numeric, selects the nth palette of type type. If character, selects the named palette. Get a complete list of all parameters by running \code{RColorBrewer::display.brewer.all(n=8, exact.n=FALSE)}}
\item{type}{Type of scale. One of 'div' (diverging), 'qual' (qualitative, the default), 'seq' (sequential), or 'all' (all). Only used when palette is numeric.}
\item{na.colour}{colour to use for missing values}
\item{limits}{numeric vector of length 2, giving the extent of the scale}
\item{breaks}{numeric vector indicating where breaks should lie}
\item{labels}{character vector giving labels associated with breaks}
\item{formatter}{NULL}
\item{legend}{NULL}
\item{...}{other arguments}

# scale_colour_brewer but for fill colours
