#' Differentiation related aesthetics: linetype, size, shape
#'
#' @description
#' The `linetype`, `size`, and `shape` aesthetics modify the appearance of
#' lines and/or points. They also apply to the outlines of polygons (`linetype`
#' and `size`) or to text (`size`).
#'
#' The `linetype` aesthetic can be specified with either an integer (0-6), a
#' name (0 = blank, 1 = solid, 2 = dashed, 3 = dotted, 4 = dotdash, 5 = longdash,
#' 6 = twodash), a mapping to a discrete variable, or a string of an even number
#' (up to eight) of hexadecimal digits which give the lengths in consecutive
#' positions in the string. See examples for a hex string demonstration.
#'
#' The `size` aesthetic can be specified with a numerical value (in millimetres)
#' or via a mapping to a continuous variable.
#'
#' The `shape` aesthetic can be specified with an integer (between 0 and 25),
#' a single character (which uses that character as the plotting symbol),
#' a `.` to draw the smallest rectangle that is visible (i.e., about one pixel),
#' an `NA` to draw nothing, or a mapping to a discrete variable. Symbols and
#' filled shapes are described in the examples below.

#' * [geom_line()] and [geom_point()] for geoms commonly used
#' with these aesthetics.
#' * [aes_group_order()] for using `linetype`, `size`, or
#' `shape` for grouping.
#' * Run `vignette("ggplot2-specs")` to see an overview of other aesthestics that
#' can be modified.
