Geom for drawing diamond plot representing lattice structures

This function creates a ggplot2 geom for drawing diamond plots, which are used to visualize lattice structures in data. This is useful especially for visualization of rules and its ancestors.

Usage

geom_diamond(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  na.rm = FALSE,
  linetype = "solid",
  nudge_x = 0,
  nudge_y = 0.125,
  show.legend = NA,
  inherit.aes = TRUE,
  ...
)

Arguments

mapping: Aesthetic mappings, usually created with aes().
data: A data frame containing the data to be plotted.
stat: The statistical transformation to use on the data, default is "identity".
position: Position adjustment, default is "identity".
na.rm: A logical value indicating whether to remove missing values.
linetype: The type of line to use for the edges, default is "solid".
nudge_x: Horizontal nudge for the x-coordinates of the labels.
nudge_y: Vertical nudge for the y-coordinates of the labels.
show.legend: A logical value indicating whether to show the legend.
inherit.aes: A logical value indicating whether to inherit aesthetics from the plot.
...: Other arguments passed to the layer.

Value

A ggplot2 layer object that can be added to a ggplot.

Details

The diamonds represent items in the lattice, and edges represent an inclusion relationship between them.
