In ggrastr: Rasterize Layers for 'ggplot2'

This geom is similar to geom_violin, but creates a raster layer

Description

This geom is similar to geom_violin, but creates a raster layer

Usage

geom_violin_rast(
  ...,
  raster.dpi = getOption("ggrastr.default.dpi", 300),
  dev = "cairo",
  scale = 1
)

Arguments

...	Other arguments passed on to layer(). These are often aesthetics, used to set an aesthetic to a fixed value, like colour = "red" or size = 3. They may also be parameters to the paired geom/stat.
raster.dpi	integer Resolution of the rastered image in dots per inch (default=300).
dev	string Specifies the device used, which can be one of: "cairo", "ragg" or "ragg_png" (default="cairo").
scale	numeric Scaling factor to modify the raster object size (default=1). The parameter 'scale=1' results in an object size that is unchanged, 'scale'>1 increase the size, and 'scale'<1 decreases the size. These parameters are passed to 'height' and 'width' of grid::grid.raster(). Please refer to 'rasterise()' and 'grid::grid.raster()' for more details.

Value

geom_violin_rast plot with rasterized layer

Aesthetics

geom_violin() understands the following aesthetics (required aesthetics are in bold):

• x

• y

• alpha

• colour

• fill

• group

• linetype

• linewidth

• weight

Learn more about setting these aesthetics in vignette("ggplot2-specs").

Examples

library(ggplot2)
library(ggrastr)

ggplot(mpg) + geom_violin_rast(aes(x = factor(cyl), y = hwy), raster.dpi = 600)
