Arguments

data

An tibble or dataframe. Required input.

x_var

Unquoted numeric, date or categorical variable to be on the x axis. Required input.

y_var

Unquoted numeric variable to be on the y axis. Defaults to NULL. Required if stat equals "boxplot".

facet_var

Unquoted categorical variable to facet the data by. Required input.

stat

String of "boxplot" or "identity". Defaults to "boxplot". If identity is selected, data provided must be grouped by the x_var and facet_var with ymin, lower, middle, upper, ymax variables. Note "identity" does not provide outliers.

pal

Character vector of hex codes. Defaults to viridis. Use the pals package to find a suitable palette.

width

Width of the box. Defaults to 0.5.

alpha

The alpha of the fill. Defaults to 1.

size_line

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

size_point

The size of the outliers. Defaults to 1.

title

Title string. Defaults to NULL.

title_wrap

Number of characters to wrap the title to. Defaults to 70.

subtitle

Subtitle string. Defaults to "[Subtitle]".

subtitle_wrap

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

x_balance

For a numeric x variable, add balance to the x scale so that zero is in the centre. Defaults to FALSE.

x_expand

Adjust the vector of range expansion constants used to add some padding on the x scale.

x_labels

Adjust the x scale labels through a function that takes the breaks as input and returns labels as output.

x_pretty_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 6.

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.

x_zero

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

x_zero_line

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

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_expand

Adjust the vector of range expansion constants used to add some padding on the y scale.

y_labels

Adjust the y scale labels through a function that takes the breaks as input and returns labels as output.

y_pretty_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_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_trans

For a numeric y variable, a string specifying a transformation for the y scale, such as "log10" or "sqrt". Defaults to "identity".

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.

facet_ncol

The number of columns of facetted plots.

facet_nrow

The number of rows of facetted plots.

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".

caption

Caption title string. Defaults to NULL.

caption_wrap

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

font_family

Font family to use. Defaults to "Helvetica".

font_size_title

Font size for the title text. Defaults to 11.

font_size_body

Font size for all text other than the title. Defaults to 10.

Value

A ggplot object.

Examples

library(dplyr) plot_data <- ggplot2::diamonds %>% mutate(price_thousands = (price / 1000)) ggplot_boxplot_facet(plot_data, cut, price_thousands, color)
