\arguments{
\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 An expression vector (must be the same length as breaks). See ?plotmath for details.
\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[ggplot2:coord_cartesian]{coord_cartesian()}}).
}}
\item{range}{a numeric vector of length 2 that specifies the minimum and
maximum size of the plotting symbol after transformation.}
\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{guide}{A function used to create a guide or its name. See
\code{\link[ggplot2:guides]{guides()}} for more information.}
\item{...}{
Arguments passed on to \code{\link[ggplot2:continuous_scale]{continuous_scale}}
\describe{
\item{\code{minor_breaks}}{One of:
\itemize{
\item \code{NULL} for no minor breaks
\item \code{waiver()} for the default breaks (one minor break between
each major break)
\item A numeric vector of positions
\item A function that given the limits returns a vector of minor breaks. Also
accepts rlang \link[rlang:as_function]{lambda} function notation.
}}
\item{\code{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{\code{na.value}}{Missing values will be replaced with this value.}
\item{\code{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[ggplot2: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{\code{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{\code{super}}{The super class to use for the constructed scale}
}}
\item{n.breaks}{An integer guiding the number of major breaks. The algorithm
may choose a slightly different number to ensure nice break labels. Will
only have an effect if \code{breaks = waiver()}. Use \code{NULL} to use the default
number of breaks given by the transformation.}
\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{values}{a set of aesthetic values to map data values to. The values
will be matched in order (usually alphabetical) with the limits of the
scale, or with \code{breaks} if provided. If this is a named vector, then the
values will be matched based on the names instead. Data values that don't
match will be given \code{na.value}.}
\item{na.value}{The aesthetic value to use for missing (\code{NA}) values}
}
\value{
A ggproto object inheriting from \code{Scale}
}
\description{
This set of scales defines new size scales for edge labels in order to allow
for separate sizing of edges and their labels.
