set_xtras_options: Set 'xpose.xtras' session options

In xpose.xtras: Extra Functionality for the 'xpose' Package

Set xpose.xtras session options

Description

Convenience wrapper around base options() for the ⁠xpose.xtras.*⁠ family of options recognized by this package. Prefixes are added automatically and names are validated against the list below, so e.g. set_xtras_options(save_dir = "figures") is equivalent to (but safer against typos than) options(xpose.xtras.save_dir = "figures"). Current values can be read back with regular getOption() (e.g. getOption("xpose.xtras.save_dir")), or with get_xtras_option() for default_labs/default_watermark, which also considers any xpdb-level default.

Usage

set_xtras_options(...)

Arguments

...	<dynamic-dots> One or more of default_labs, default_watermark, save_dir, save_width, save_height, save_fun, gg_theme, xp_theme, given as name = value

Details

Recognized options (all unset, i.e. NULL, by default, except auto_apply which defaults to TRUE):

auto_apply

Whether print.xpose_plot() and ggsave_xp() automatically apply configured default_labs/ default_watermark (labels always; a watermark only if default_watermark is actually set at some tier – there's no unprompted default watermark). Defaults to TRUE, but is a no-op until default_labs/default_watermark are themselves configured, so leaving it at its default has no visible effect on its own; set it to FALSE to opt out of the auto-apply behavior everywhere at once (or pass apply_labs/apply_watermark to a specific ggsave_xp() call to opt out just there). print.xpose_plot() only ever sees the session-wide option tier (not an xpdb-level one) for the same reason noted under default_labs below.

default_labs

Named list of default title/subtitle/ caption/tag templates (may contain ⁠@keyword⁠ placeholders, see xpose::parse_title()). Used by apply_default_labs() (and by extension ggsave_xp()) as the lowest-precedence source for any label a plot doesn't already have – xpdb-level defaults (see set_default_labs()) and arguments passed directly to apply_default_labs() both take precedence over this option.

default_watermark

Named list of default add_watermark() arguments (any of label/colour/alpha/size/angle/ fontface). Used by add_watermark() as the lowest-precedence source – xpdb-level defaults (see set_default_watermark()) and arguments passed directly to add_watermark() both take precedence over this option.

default_plots

A list of plot specs (see plot.xpose_data()) used whenever plots isn't supplied directly to plot.xpose_data(). Unlike default_labs/ default_watermark, this is resolved as a whole (not merged key by key) – xpdb-level defaults (see set_default_plots()) take precedence over this option, and a plots argument passed directly takes precedence over both.

save_dir, save_width, save_height

Defaults for the path/width/height arguments of ggsave_xp(), used whenever those arguments aren't supplied explicitly.

save_fun

Default save function for ggsave_xp() (itself defaulting to ggplot2::ggsave() when this is unset), for swapping in a drop-in alternative such as reportifyr::ggsave_with_metadata() project-wide instead of passing save_fun to every ggsave_xp() call.

gg_theme, xp_theme

Default ggplot2 theme / xpose xp_theme (see xpose::update_themes()) applied to an xpose_data object the first time it's converted via as_xpdb_x(), so a project-wide look can be set once per session instead of calling xpose::update_themes() on every xpdb individually. Has no effect on xpdbs that are already xp_xtras objects.

Value

the previous values of the options that were set, invisibly (see options())

See Also

get_xtras_option() to inspect which tier is currently dominant for a two-tier option; apply_default_labs(), add_watermark(), ggsave_xp(), and as_xpdb_x(), which consume these options.

Examples

set_xtras_options(save_dir = "figures", default_watermark = list(label = "DRAFT"))
getOption("xpose.xtras.save_dir")
set_xtras_options(save_dir = NULL, default_watermark = NULL)
