Create a ggformula layer function — layer

Primarily intended for package developers, this function factory is used to create the layer functions in the ggformula package.

Usage

layer_factory(
  geom = "point",
  position = "identity",
  stat = "identity",
  interactive = FALSE,
  layer_func_interactive = "geom_point",
  pre = {
 },
  aes_form = y ~ x,
  extras = alist(),
  note = NULL,
  aesthetics = aes(),
  inherit.aes = TRUE,
  check.aes = TRUE,
  data = NULL,
  layer_fun = if (interactive) {
     quo(layer_interactive)
 } else {
    
    quo(ggplot2::layer)
 },
  ...
)

Arguments

geom: The geom to use for the layer (may be specified as a string).
position: The position function to use for the layer (may be specified as a string).
stat: The stat function to use for the layer (may be specified as a string).
interactive: A logical indicating whether this is being used to create an interactive layer.
layer_func_interactive: The function used to create the layer when `interactive“ is TRUE (or a quosure that evaluates to such a function).
pre: code to run as a "pre-process".
aes_form: A single formula or a list of formulas specifying how attributes are inferred from the formula. Use NULL if the function may be used without a formula.
extras: An alist of additional arguments (potentially with defaults)
note: A note to add to the quick help.
aesthetics: Additional aesthetics (typically created using ggplot2::aes()) set rather than inferred from formula. gf_dhistogram() uses this to set the y aesthetic to stat(density), for example.
inherit.aes: A logical indicating whether aesthetics should be inherited from prior layers or a vector of character names of aesthetics to inherit.
check.aes: A logical indicating whether a warning should be emited when aesthetics provided don't match what is expected.
data: A data frame or NULL or NA.
layer_fun: function used to create a layer. The default value is anticipated to work in most (all?) cases.
...: Additional arguments.

Value

A function.
