  x_minor = NULL,
  y_major = NULL,
  y_minor = NULL,
  x_scale = identity,
  y_scale = identity,
  polar = FALSE,
  width = ggplot2::rel(2.1),
  height = ggplot2::rel(1.8),
  global_rescale = TRUE,
  show.legend = NA,
  inherit.aes = TRUE
)

geom_glyph_line(
  mapping = NULL,
  data = NULL,
  stat = "identity",

)

geom_glyph_box(
  mapping = NULL,

  show.legend = NA,
  inherit.aes = TRUE
)

Arguments

mapping	Set of aesthetic mappings created by aes(). If specified and inherit.aes = TRUE (the default), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping.
data	The data to be displayed in this layer. There are three options: If NULL, the default, the data is inherited from the plot data as specified in the call to ggplot(). A data.frame, or other object, will override the plot data. All objects will be fortified to produce a data frame. See fortify() for which variables will be created. A function will be called with a single argument, the plot data. The return value must be a data.frame, and will be used as the layer data. A function can be created from a formula (e.g. ~ head(.x, 10)).
stat	The statistical transformation to use on the data for this layer, either as a ggproto Geom subclass or as a string naming the stat stripped of the stat_ prefix (e.g. "count" rather than "stat_count")
position	Position adjustment, either as a string naming the adjustment (e.g. "jitter" to use position_jitter), or the result of a call to a position adjustment function. Use the latter if you need to change the settings of the adjustment.
...	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.
x_major, x_minor, y_major, y_minor	The name of the variable (as a string) for the major and minor x and y axes. Together, each unique combination of x_major and y_major specifies a grid cell.
y_scale, x_scale	The scaling function to be applied to each set of minor values within a grid cell. Defaults to identity so that no scaling is performed.
polar	A logical of length 1, specifying whether the glyphs should be drawn in polar coordinates. Defaults to FALSE.
height, width	The height and width of each glyph. Defaults to 95% of the resolution of the data. Specify the width absolutely by supplying a numeric vector of length 1, or relative to the resolution of the data by using rel.
global_rescale	Whether rescale is performed globally or on each individual glyph.
show.legend	logical. Should this layer be included in the legends? NA, the default, includes if any aesthetics are mapped. FALSE never includes, and TRUE always includes. It can also be a named logical vector to finely select the aesthetics to display.
inherit.aes	If FALSE, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g. borders().

Value

a ggplot object
