2D density contour layer — mark_density

Adds 2D kernel density estimate contours. Use filled = TRUE for filled density bands via ggplot2::geom_density_2d_filled.

Usage

mark_density_2d(
  plot,
  mapping = NULL,
  data = NULL,
  position = NULL,
  ...,
  filled = FALSE,
  bins = NULL,
  rasterize = FALSE,
  rasterize_dpi = 300,
  rasterize_dev = "cairo"
)

Arguments

plot: A plotit object
mapping: Optional new aesthetics
data: Optional data for this layer
position: Position adjustment.
...: Other arguments passed to the underlying geom
filled: If TRUE, use filled density contours.
bins: Number of contour bins (for filled mode).
rasterize: If TRUE, rasterize via ggrastr::rasterise().
rasterize_dpi: DPI for rasterization (default 300).
rasterize_dev: Graphics device for rasterization (default "cairo").

Value

Modified plotit object
