grid.pattern_none() draws nothing onto the graphic device.

Usage

grid.pattern_none(
  x = c(0, 0, 1, 1),
  y = c(1, 0, 0, 1),
  id = 1L,
  ...,
  default.units = "npc",
  name = NULL,
  gp = gpar(),
  draw = TRUE,
  vp = NULL
)

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

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).

Value

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

Examples

x_hex <- 0.5 + 0.5 * cos(seq(2 * pi / 4, by = 2 * pi / 6, length.out = 6))
y_hex <- 0.5 + 0.5 * sin(seq(2 * pi / 4, by = 2 * pi / 6, length.out = 6))
grid.pattern_none(x_hex, y_hex)
