Polygon tiling patterned grobs

grid.pattern_polygon_tiling() draws a specified polygon tiling pattern onto the graphic device. names_polygon_tiling lists all supported types.

grid.pattern_polygon_tiling(
  x = c(0, 0, 1, 1),
  y = c(1, 0, 0, 1),
  id = 1L,
  ...,

  xoffset = 0,
  yoffset = 0,

names_polygon_tiling

Arguments

x	A numeric vector or unit object specifying x-locations of the pattern boundary.
y	A numeric vector or unit object specifying y-locations of the pattern boundary.
id	A numeric vector used to separate locations in x, y into multiple boundaries. All locations within the same `id` belong to the same boundary.
...	Currently ignored
colour	Stroke colour
fill	Fill colour
angle	Rotation angle in degrees
spacing	Spacing between repetitions of pattern ('snpc' units between 0 and 1).
xoffset	Shift pattern along x axis ('snpc' units between 0 and 1).
yoffset	Shift pattern along y axis ('snpc' units between 0 and 1).
type	Name of polygon tiling to draw. See Details.
alpha	Alpha (between 0 and 1) or `NA` (default, preserves colors' alpha value). Not supported for all polygon tiling `type`.
linetype	Stroke linetype
size	Stroke linewidth
default.units	A string indicating the default units to use if `x` or `y` are only given as numeric vectors.
name	A character identifier.
gp	An object of class `"gpar"`, typically the output from a call to the function `gpar`. This is basically a list of graphical parameter settings.
draw	A logical value indicating whether graphics output should be produced.
vp	A Grid viewport object (or NULL).

Format

An object of class character of length 35.

Value

A grid grob object invisibly. If draw is TRUE then also draws to the graphic device as a side effect.

Details

grid.pattern_polygon_tiling() supports 1, 2, or 3 fill colors with the first colors (weakly) covering a larger area. Size of the pattern is controlled by spacing. We support the following polygon tiling types:

herringbone: Creates a herringbone tiling made of rectangles.
hexagonal: Creates a hexagonal tiling made of hexagons.
pythagorean: Creates a Pythagorean tiling made of squares of two different sizes.
rhombille: Creates a rhombille tiling made of rhombi.
rhombitrihexagonal: Creates a rhombitrihexagonal tiling made out of dodecagons, hexagons, and squares.
snub_square: Creates a snub square tiling made of squares and triangles.
snub_trihexagonal: Creates a snub trihexagonal tiling made of hexagons and triangles.
square: Creates a square tiling made of squares.
tetrakis_square: Creates a tetrakis square tiling made of isosceles right triangles.
triangular: Creates a triangular tiling made of equilateral triangles.
trihexagonal: Creates a trihexagonal tiling made of hexagons and triangles.
truncated_square: Creates a truncated square tiling made of octagons and squares.
truncated_hexagonal: Creates a truncated hexagonal tiling made of dodecagons and triangles.
truncated_trihexagonal: Creates a truncated trihexagonal tiling made of hexagons, squares, and triangles.
2*.2**.2*.2**: Creates a polygon tiling made of rhombi.
2**.3**.12*: Creates a polygon tiling made of rhombi, triangles, and twelve-pointed stars.
3.3.3.3**: Creates a polygon tiling made of triangles.
3.3*.3.3**: Creates a regular (star) polygon tiling made of triangles and three-pointed stars.
3.3.3.12*.3.3.12*: Creates a regular (star) polygon tiling made of triangles and twelve-pointed stars.
3.3.8*.3.4.3.8*: Creates a regular (star) polygon tiling made of triangles, squares, and eight-pointed stars.
3.3.8*.4**.8*: Creates a regular (star) polygon tiling made of triangles, four-pointed stars, and eight-pointed stars.
3.4.6.3.12*: Creates a regular (star) polygon tiling made of triangles, squares, hexagons, and twelve-pointed stars.
3.4.8.3.8*: Creates a regular (star) polygon tiling made of triangles, squares, octagons, and eight-pointed stars.
