eulerr_options: Get or set global graphical parameters for eulerr

In eulerr: Area-Proportional Euler and Venn Diagrams with Ellipses

Get or set global graphical parameters for eulerr

Description

This function provides a means to set default parameters for functions in eulerr. Query eulerr_options() (without any argument) to see all the available options and read more about the plot-related ones in grid::gpar() and graphics::par().

Usage

eulerr_options(...)

Arguments

...	objects to update the global graphical parameters for eulerr with.

Details

Currently, the following items will be considered:

pointsize

size in pts to be used as basis for fontsizes and some margin sizes in the resulting plot

#'

fills

a list of items fill and alpha

patterns

a list of items type, angle, col, lwd, and alpha

edges

a list of items col, alpha, lex, lwd, and lty

labels

a list of items rot, col, alpha, fontsize, cex, fontfamily, fontface, lineheight, and font

quantities

a list of items type, template, format, total, rot, col, alpha, fontsize, cex, fontfamily, lineheight, and font

annotations

a list of items rot, col, alpha, fontsize, cex, fontfamily, lineheight, font, and labels (a named character vector keyed by subset name). Used to add a third stacked text element per region below the quantity.

strips

col, alpha, fontsize, cex, fontfamily, lineheight, and font

legend

arguments to grid::legendGrob() as well as col, alpha, fontsize, cex, symbol_size (symbol size multiplier, independent of text size; defaults to cex if NULL), fontfamily, lineheight, and font

main

arguments to grid::textGrob()

complement

a list of styling defaults for the container box and its complement label drawn when euler() is called with ⁠complement =⁠. Items: fill, alpha, col, lty, lwd, lex, fontsize, cex, font, fontfamily, lineheight. The default lty = 2 draws the container with a dashed outline.

padding

a grid::unit() giving the padding between various elements in plots from plot.euler(), which you can change if you, for instance, want to increase spacing between labels, quantities, and percentages.

composition

a list controlling how eulergram objects are arranged when composed via | or /. Contains a single spacing item (a grid::unit()) that sets the gap between adjacent plots.

Value

This function gets or sets updates in the global environment that are used in plot.euler().
