`grid.pattern_plasma()`

draws a plasma pattern onto the graphic device.

grid.pattern_plasma(
x = c(0, 0, 1, 1),
y = c(1, 0, 0, 1),
id = 1L,
...,
fill = gp$fill %||% "grey80",
scale = 1,
alpha = gp$alpha %||% NA_real_,
aspect_ratio = 1,
key_scale_factor = 1,
res = getOption("ggpattern_res", 72),
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 |

fill |
Fill colour |

scale |
Extra scaling |

alpha |
Alpha (between 0 and 1) or `NA` (default, preserves colors' alpha value). |

aspect_ratio |
Override aspect ratio |

key_scale_factor |
Additional scale factor for legend |

res |
Assumed resolution (in pixels per graphic device inch) to use when creating array pattern. |

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.
