\title{Create customizable legend key glyphs}
\usage{
rectangle_key_glyph(
colour = NA,
fill = fill,
alpha = alpha,
size = size,
linetype = linetype,
padding = unit(c(0, 0, 0, 0), "pt"),
color
)
circle_key_glyph(
colour = NA,
fill = fill,
alpha = alpha,
size = size,
linetype = linetype,
padding = unit(c(0, 0, 0, 0), "pt"),
color
)
}
\arguments{
\item{colour, color}{Unquoted name of the aesthetic to use for the outline color,
usually \code{colour}, \code{color}, or \code{fill}. Can also be a color constant, e.g. \code{"red"}.}
\item{fill}{Unquoted name of the aesthetic to use for the fill color,
usually \code{colour}, \code{color}, or \code{fill}. Can also be a color constant, e.g. \code{"red"}.}
\item{alpha}{Unquoted name of the aesthetic to use for alpha,
usually \code{alpha}. Can also be a numerical constant, e.g. \code{0.5}.}
\item{size}{Unquoted name of the aesthetic to use for the line thickness of the
outline, usually \code{size}. Can also be a numerical constant, e.g. \code{0.5}.}
\item{linetype}{Unquoted name of the aesthetic to use for the line type of the
outline, usually \code{linetype}. Can also be a constant, e.g. \code{2}.}
\item{padding}{Unit vector with four elements specifying the top, right, bottom,
and left padding from the edges of the legend key to the edges of the key glyph.}
}
\description{
These functions create customizable legend key glyphs, such as filled rectangles or
circles.
