Arguments

data

A data frame or tibble.

...

Other arguments passed to within a params list in layer().

stat

A statistical transformation to use on the data. A snakecase character string of a ggproto Stat subclass object minus the Stat prefix (e.g. "identity").

position

A position adjustment. A snakecase character string of a ggproto Position subclass object minus the Position prefix (e.g. "identity"), or a position_*() function that outputs a ggproto Position subclass object (e.g. ggplot2::position_identity()).

coord

A coordinate system. A coord_*() function that outputs a constructed ggproto Coord subclass object (e.g. ggplot2::coord_cartesian()).

theme

A ggplot2 theme (e.g. light_mode_t() or dark_mode_r()). (Or a list that includes 1. a theme and 2. a ggplot2::labs() function. E.g. list(light_mode_r(), labs(colour = NULL, fill = NULL)).

theme_orientation

The orientation of plot, which affects the theme components that are removed. Either "x" or "y".

theme_axis_line_rm

TRUE or FALSE of whether to remove the relevant axis line per the theme_orientation of the plot.

theme_axis_ticks_rm

TRUE or FALSE of whether to remove the relevant axis ticks per the theme_orientation of the plot.

theme_panel_grid_rm

TRUE or FALSE of whether to remove the relevant panel grid per the theme_orientation of the plot.

blend

The blending mode per ggblend::blend() (e.g. "multiply").

x, xmin, xmax, xend, y, ymin, ymax, yend, z, col, facet, facet2, group, subgroup, label, text, sample

An unquoted aesthetic variable.

mapping

A set of additional aesthetic mappings in ggplot2::aes(). Intended primarily for non-supported aesthetics (e.g. shape, linetype, linewidth, or size), but can also be used for delayed evaluation etc.

x_breaks, y_breaks, col_breaks

A scales::breaks_* function (e.g. scales::breaks_*()), or a vector of breaks.

x_breaks_n, y_breaks_n, col_breaks_n

A number of desired breaks for when *_breaks = NULL.

x_expand, y_expand

Padding to the limits with the ggplot2::expansion() function, or a vector of length 2 (e.g. c(0, 0)).

x_limits_include, y_limits_include, col_limits_include

For a continuous variable, any values that the limits should encompass (e.g. 0). For a discrete scale, manipulate the data instead with forcats::fct_expand.

x_label, y_label, col_label

Label for the axis or legend title. Use + ggplot2::labs(... = NULL) for no title.

x_labels, y_labels, col_labels, facet_labels

A function that takes the breaks as inputs (e.g. \(x) stringr::str_to_sentence(x) or scales::label_*()), or a vector of labels. (Note this must be named for facet_labels).

x_position, y_position

The position of the axis (i.e. "left", "right", "bottom" or "top").If using y_position = "top" with a *_theme_* theme, add caption = "" or caption = "\n".

x_sec_axis, y_sec_axis

A secondary axis with ggplot2::dup_axis() or ggplot2::sec_axis().

x_symmetric, y_symmetric

TRUE or FALSE of whether a symmetric scale.

x_transform, y_transform, col_transform

For a continuous scale, a transformation object (e.g. scales::transform_log10()) or character string of this minus the transform_ prefix (e.g. "log10").

col_drop, facet_drop

For a discrete variable, FALSE or TRUE of whether to drop unused levels.

col_legend_ncol, col_legend_nrow

The number of columns and rows in a legend guide.

col_legend_rev

TRUE or FALSE of whether to reverse the elements of a legend guide. Defaults to FALSE.

col_palette

A character vector of hex codes (or names) or a scales::pal_*() function.

col_palette_na

A hex code (or name) for the colour of NA values.

col_rescale

For a continuous variable, a scales::rescale() function.

col_steps

For a continuous variable, TRUE or FALSE of whether to colour in steps. Defaults to FALSE.

facet_axes

Whether to add interior axes and ticks with "margins", "all", "all_x", or "all_y". Sometimes + *_theme_*() may be needed.

facet_axis_labels

Whether to add interior axis labels with "margins", "all", "all_x", or "all_y".

facet_layout

Whether the layout is to be "wrap" or "grid". If NULL and a single facet (or facet2) argument is provided, then defaults to "wrap". If NULL and both facet and facet2 arguments are provided, defaults to "grid".

facet_ncol, facet_nrow

The number of columns and rows of facet panels. Only applies to a facet layout of "wrap".

facet_scales

Whether facet scales should be "fixed" across facets, "free" in both directions, or free in just one direction (i.e. "free_x" or "free_y"). Defaults to "fixed".

facet_space

When the facet scales are not "fixed", whether facet space should be "fixed" across facets, "free" to be proportional in both directions, or free to be proportional in just one direction (i.e. "free_x" or "free_y"). Defaults to "fixed".

title

Title string.

subtitle

Subtitle string.

caption

Caption title string.

label_case

A function to format the label of unlabelled variables. Defaults to snakecase::to_sentence_case.

Value

A ggplot object.
