layer_factory

Create a ggformula layer function

Description

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",
  pre = { },
  aes_form = y ~ x,
  extras = alist(),
  note = NULL,
  aesthetics = aes(),
  inherit.aes = TRUE,
  check.aes = TRUE,
  data = NULL,
  layer_fun = 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).
`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`	The function used to create the layer or a quosure that evaluates to such a function.
`...`	Additional arguments.

Value

A function.
