Initialize Quad-Layout Annotation

Initializes an annotation stack with a user-specified data.

Usage

quad_init(position, data = waiver(), ...)

Arguments

position

A string of "top", "left", "bottom", or "right" indicates which annotation stack should be initialized.

data

Default dataset to use for the annotation stack. If not specified, a dataset must be provided for each plot added to the layout. Possible values:

• waiver(): try to inherit from the quad_layout().

• NULL: no data for the annotation stack.

• Any data which can be coerced by fortify_matrix()/fortify_data_frame()

Data conversion depends on whether the annotation stack will align the observations:

• If aligned, fortify_matrix() will be applied to convert the data into a matrix.

• If not aligned, fortify_data_frame() will be used to convert the data into a data frame.

Additional arguments passed to fortify_matrix() or fortify_data_frame().
