Arguments

data

An ungrouped summarised tibble or dataframe generally in a structure to be transformed to boxplot statistics (or alternatively in a structure of summary boxplot statistics). Required input.

x_var

Unquoted categorical variable to be on the x scale (i.e. character, factor, logical). Required input.

y_var

Unquoted numeric variable to be on the y scale for when stat = "boxplot" is selected.

pal

Character vector of hex codes.

alpha_fill

The opacity of the fill. Defaults to 0.5.

alpha_line

The opacity of the outline. Defaults to 1.

alpha_point

The opacity of the outlier points. Defaults to 1.

size_line

The size of the outlines of boxplots. Defaults to 0.5.

size_point

The size of the outlier points. Defaults to 1.5.

size_width

Width of boxes. Defaults to 0.5.

title

Title string.

title_wrap

Number of characters to wrap the title to. Defaults to 75.

subtitle

Subtitle string.

subtitle_wrap

Number of characters to wrap the subtitle to. Defaults to 75.

x_expand

A vector of range expansion constants used to add padding to the x scale, as per the ggplot2 expand argument in ggplot2 scales functions.

x_labels

A function or named vector to modify x scale labels. If NULL, categorical variable labels are converted to sentence case. Use ggplot2::waiver() to keep x labels untransformed.

x_na_rm

TRUE or FALSE of whether to include x_var NA values. Defaults to FALSE.

x_rev

For a categorical x variable, TRUE or FALSE of whether the x variable variable is reversed. Defaults to FALSE.

x_title

x scale title string. Defaults to NULL, which converts to sentence case with spaces. Use "" if you would like no title.

x_title_wrap

Number of characters to wrap the x title to. Defaults to 50.

y_balance

For a numeric y variable, add balance to the y scale so that zero is in the centre of the y scale.

y_breaks_n

For a numeric or date x variable, the desired number of intervals on the x scale, as calculated by the pretty algorithm. Defaults to 5.

y_expand

A vector of range expansion constants used to add padding to the y scale, as per the ggplot2 expand argument in ggplot2 scales functions.

y_labels

A function or named vector to modify y scale labels. Use ggplot2::waiver() to keep y labels untransformed.

y_title

y scale title string. Defaults to NULL, which converts to sentence case with spaces. Use "" if you would like no title.

y_title_wrap

Number of characters to wrap the y title to. Defaults to 50.

y_zero

For a numeric y variable, TRUE or FALSE of whether the minimum of the y scale is zero. Defaults to TRUE.

y_zero_line

For a numeric y variable, TRUE or FALSE whether to add a zero reference line to the y scale. Defaults to TRUE if there are positive and negative values in y_var. Otherwise defaults to FALSE.

caption

Caption title string.

caption_wrap

Number of characters to wrap the caption to. Defaults to 80.

stat

String of "boxplot" or "identity". Defaults to "boxplot".

ymin_var

Unquoted numeric variable for minimum of whisker on the y scale for when stat = "identity" is selected.

ylower_var

Unquoted numeric variable for minimum of box on the y scale for when stat = "identity" is selected.

ymiddle_var

Unquoted numeric variable for middle of box on the y scale for when stat = "identity" is selected.

yupper_var

Unquoted numeric variable for maximum of box on the y scale for when stat = "identity" is selected.

ymax_var

Unquoted numeric variable for maximum of whisker on the y scale for when stat = "identity" is selected.

theme

A ggplot2 theme.

mobile

Whether the plot is to be displayed on a mobile device. Defaults to FALSE.

Value

A ggplot object.
