Named values to update options with, or unnamed option names to retrieve. To query all options, call without arguments.

Details

Currently supported options are nested under the plot key:

• spacing: A grid::unit() controlling space between composed plots (default: grid::unit(1, "lines"))

• node_style: List of default node appearance parameters:

  • fill: Fill color (default: "lightgrey")

  • padding: Padding around labels in mm (default: 2)

  • size: Size multiplier (default: 1)

• edge_style: List of default edge appearance parameters:

  • arrow_size: Arrow size in mm (default: 3)

  • circle_size: Radius of endpoint circles for partial edges in mm (default: 1.5)

  • fill: Arrow/line color (default: "black")

• label_style: List of label text parameters (see grid::gpar())

• title_style: List of title text parameters:

  • col: Text color (default: "black")

  • fontface: Font face (default: "bold")

  • fontsize: Font size in pts (default: 14.4)

Options set via caugi_options() serve as global defaults that can be overridden by arguments to plot().
