\arguments{
\item{...}{
Arguments passed on to \code{\link[ggplot2:discrete_scale]{discrete_scale}}
\describe{
\item{\code{palette}}{A palette function that when called with a single integer
argument (the number of levels in the scale) returns the values that
they should take (e.g., \code{\link[scales:pal_hue]{scales::pal_hue()}}).}
\item{\code{breaks}}{One of:
\itemize{
\item \code{NULL} for no breaks
\item \code{waiver()} for the default breaks (the scale limits)
\item A character vector of breaks
\item A function that takes the limits as input and returns breaks
as output. Also accepts rlang \link[rlang:as_function]{lambda} function
notation.
}}
\item{\code{limits}}{One of:
\itemize{
\item \code{NULL} to use the default scale values
\item A character vector that defines possible values of the scale and their
order
\item A function that accepts the existing (automatic) values and returns
new ones. Also accepts rlang \link[rlang:as_function]{lambda} function
notation.
}}
\item{\code{drop}}{Should unused factor levels be omitted from the scale?
The default, \code{TRUE}, uses the levels that appear in the data;
\code{FALSE} uses all the levels in the factor.}
\item{\code{na.translate}}{Unlike continuous scales, discrete scales can easily show
missing values, and do so by default. If you want to remove missing values
from a discrete scale, specify \code{na.translate = FALSE}.}
\item{\code{aesthetics}}{The names of the aesthetics that this scale works with.}
\item{\code{scale_name}}{\ifelse{html}{\href{https://lifecycle.r-lib.org/articles/stages.html#deprecated}{\figure{lifecycle-deprecated.svg}{options: alt='[Deprecated]'}}}{\strong{[Deprecated]}} The name of the scale
that should be used for error messages associated with this scale.}
\item{\code{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{\code{guide}}{A function used to create a guide or its name. See
\code{\link[ggplot2:guides]{guides()}} for more information.}
\item{\code{call}}{The \code{call} used to construct the scale for reporting messages.}
\item{\code{super}}{The super class to use for the constructed scale}
}}
\item{na.value}{The linetype to use for \code{NA} values.}
\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{breaks}{One of:
\itemize{
\item \code{NULL} for no breaks
\item \code{waiver()} for the default breaks (the scale limits)
\item A character vector of breaks
\item A function that takes the limits as input and returns breaks
as output
}}
\item{guide}{Guide to use for this scale. Defaults to \code{"none"}.}
}
\value{
A ggproto object inheriting from \code{Scale}
}
\description{
This set of scales defines new linetype scales for edge geoms equivalent to
the ones already defined by ggplot2. See
\code{\link[ggplot2:scale_linetype]{ggplot2::scale_linetype()}} for more information. The different
geoms will know whether to use edge scales or the standard scales so it is
not necessary to write \code{edge_linetype} in the call to the geom - just
use \code{linetype}.
