Constructive options for class 'Layer' (ggplot2)

Source: R/s3-ggplot2-Layer.R
opts_Layer.Rd

These options will be used on objects of class 'Layer'.

Usage

opts_Layer(constructor = c("default", "layer", "next", "environment"), ...)

Arguments

constructor

String. Name of the function used to construct the object, see Details section.

...

Should not be used. Forces passing arguments by name.

Value

An object of class <constructive_options/constructive_options_Layer>

Details

Depending on constructor, we construct the object as follows:

  • "default" : We attempt to use the function originally used to create the plot.

  • "layer" : We use the ggplot2::layer() function

  • "environment" : Reconstruct the object using the general environment method (which can be itself tweaked using opts_environment())

The latter constructor is the only one that reproduces the object exactly since Layers are environments and environments can't be exactly copied (see ?opts_environment)
