Hand-drawn theme elements

Sketch counterparts of ggplot2::element_line() and ggplot2::element_rect(). Use them in ggplot2::theme() (or via theme_sketch(rough_frame = TRUE)) to render gridlines, panel borders, and axis ticks with the same wobbly, double-stroke look as the geoms. They accept the usual element arguments plus the shared sketch parameters (roughness, bowing, n_passes, seed).

Usage

element_sketch_line(
  colour = NULL,
  linewidth = NULL,
  linetype = NULL,
  lineend = NULL,
  color = NULL,
  roughness = 0.5,
  bowing = 0.5,
  n_passes = 2L,
  seed = NULL,
  ...
)

element_sketch_rect(
  fill = NULL,
  colour = NULL,
  linewidth = NULL,
  linetype = NULL,
  color = NULL,
  roughness = 0.6,
  bowing = 0.4,
  n_passes = 2L,
  seed = NULL,
  ...
)

Arguments

colour, color

Line/border colour.

linewidth

Line width.

linetype

Line type.

lineend

Line end style.

roughness, bowing, n_passes, seed

Sketch parameters (see geom_sketch_path()). Defaults are gentle, suited to a frame.

...

Passed to the underlying ggplot2 element constructor.

fill

Fill colour (element_sketch_rect() only). NA draws the outline only — the usual choice for a panel border.

Value

A ggplot2 theme element carrying an element_sketch_* subclass.
