Constructive options for class 'Layer' (ggplot2)

Source: R/s3-ggplot2-Layer.R

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

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

Arguments

constructor

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

...

Additional options used by user defined constructors through the opts object

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)
