\arguments{
\item{aesthetics}{The names of the aesthetics that this scale works with.}

\item{scale_name}{The name of the scale that should be used for error messages
associated with this scale.}

\item{palette}{A palette function that when called with a numeric vector with
values between 0 and 1 returns the corresponding output values
(e.g., \code{\link[scales:area_pal]{scales::area_pal()}}).}

\item{name}{The name of the scale. Used as the axis or legend title. If
\code{waiver()}, the default, the name of the scale is taken from the first
mapping used for that aesthetic. If \code{NULL}, the legend title will be
omitted.}

\item{breaks}{One of:
\itemize{
\item \code{NULL} for no breaks
\item \code{waiver()} for the default breaks computed by the
\link[scales:trans_new]{transformation object}
\item A numeric vector of positions
\item A function that takes the limits as input and returns breaks
as output (e.g., a function returned by \code{\link[scales:breaks_extended]{scales::extended_breaks()}}).
Also accepts rlang \link[rlang:as_function]{lambda} function notation.
}}

\item{labels}{One of:
\itemize{
\item \code{NULL} for no labels
\item \code{waiver()} for the default labels computed by the
transformation object
\item A character vector giving labels (must be same length as \code{breaks})
\item A function that takes the breaks as input and returns labels
as output. Also accepts rlang \link[rlang:as_function]{lambda} function
notation.
}}

\item{limits}{One of:
\itemize{
\item \code{NULL} to use the default scale range
\item A numeric vector of length two providing limits of the scale.
Use \code{NA} to refer to the existing minimum or maximum
\item A function that accepts the existing (automatic) limits and returns
new limits. Also accepts rlang \link[rlang:as_function]{lambda} function
notation.
Note that setting limits on positional scales will \strong{remove} data outside of the limits.
If the purpose is to zoom, use the limit argument in the coordinate system
(see \code{\link[=coord_cartesian]{coord_cartesian()}}).
}}

\item{rescaler}{A function used to scale the input values to the
range [0, 1]. This is always \code{\link[scales:rescale]{scales::rescale()}}, except for
diverging and n colour gradients (i.e., \code{\link[=scale_colour_gradient2]{scale_colour_gradient2()}},
\code{\link[=scale_colour_gradientn]{scale_colour_gradientn()}}). The \code{rescaler} is ignored by position
scales, which always use \code{\link[scales:rescale]{scales::rescale()}}. Also accepts rlang
\link[rlang:as_function]{lambda} function notation.}

\item{oob}{One of:
\itemize{
\item Function that handles limits outside of the scale limits
(out of bounds). Also accepts rlang \link[rlang:as_function]{lambda}
function notation.
\item The default (\code{\link[scales:oob]{scales::censor()}}) replaces out of
bounds values with \code{NA}.
\item \code{\link[scales:oob]{scales::squish()}} for squishing out of bounds values into range.
\item \code{\link[scales:oob]{scales::squish_infinite()}} for squishing infinite values into range.
}}

\item{expand}{For position scales, a vector of range expansion constants used to add some
padding around the data to ensure that they are placed some distance
away from the axes. Use the convenience function \code{\link[=expansion]{expansion()}}
to generate the values for the \code{expand} argument. The defaults are to
expand the scale by 5\% on each side for continuous variables, and by
0.6 units on each side for discrete variables.}

\item{na.value}{Missing values will be replaced with this value.}

\item{n.breaks}{The number of break points to create if breaks are not given
directly.}

\item{nice.breaks}{Logical. Should breaks be attempted placed at nice values
instead of exactly evenly spaced between the limits. If \code{TRUE} (default)
the scale will ask the transformation object to create breaks, and this
may result in a different number of breaks than requested. Ignored if
breaks are given explicitly.}

\item{right}{Should values on the border between bins be part of the right
(upper) bin?}

\item{trans}{For continuous scales, the name of a transformation object
or the object itself. Built-in transformations include "asn", "atanh",
"boxcox", "date", "exp", "hms", "identity", "log", "log10", "log1p", "log2",
"logit", "modulus", "probability", "probit", "pseudo_log", "reciprocal",
"reverse", "sqrt" and "time".

A transformation object bundles together a transform, its inverse,
and methods for generating breaks and labels. Transformation objects
are defined in the scales package, and are called \verb{<name>_trans} (e.g.,
\code{\link[scales:boxcox_trans]{scales::boxcox_trans()}}). You can create your own
transformation with \code{\link[scales:trans_new]{scales::trans_new()}}.}

\item{show.limits}{should the limits of the scale appear as ticks}

\item{guide}{A function used to create a guide or its name. See
\code{\link[=guides]{guides()}} for more information.}

\item{position}{For position scales, The position of the axis.
\code{left} or \code{right} for y axes, \code{top} or \code{bottom} for x axes.}

\item{super}{The super class to use for the constructed scale}
