Arguments

data

A tibble or dataframe. Required input.

x_var

Unquoted numeric variable to be on the x scale. Required input.

facet_var

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

density_bw

The bw argument of the stats::density function. Defaults to "nrd0".

density_adjust

The adjust argument of the stats::density function. Defaults to 1.

density_kernel

The kernel argument of the stats::density function. Defaults to "gaussian".

density_n

The n argument of the stats::density function. Defaults to 512.

density_trim

The trim argument of the stats::density function. Defaults to FALSE.

pal

Character vector of hex codes.

alpha

The alpha of the fill. Defaults to 1.

size_line

The size of the outlines of density areas.

title

Title string. Defaults to NULL.

title_wrap

Number of characters to wrap the title to. Defaults to 100.

subtitle

Subtitle string.

subtitle_wrap

Number of characters to wrap the subtitle to. Defaults to 100.

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

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 vector to modify x scale labels, as per the ggplot2 labels argument in ggplot2 scales functions. If NULL, categorical variable labels are converted to sentence case. Use ggplot2::waiver() to keep x labels untransformed.

x_pretty_n

For a numeric x variable, the desired number of intervals on the x scale, as calculated by the pretty algorithm. Defaults to 3.

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_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_gridlines_minor

TRUE or FALSE of whether to add minor gridlines to the y scale. Defaults to FALSE.

y_labels

A function or vector to modify y scale labels, as per the ggplot2 labels argument in ggplot2 scales functions. If NULL, categorical variable labels are converted to sentence case. Use ggplot2::waiver() to keep y labels untransformed.

y_pretty_n

For a numeric y variable, the desired number of intervals on the y scale, as calculated by the pretty algorithm. Defaults to 4.

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.

facet_labels

As per the ggplot2 labeller argument within the ggplot facet_wrap function. If NULL, defaults to ggplot2::as_labeller(stringr::str_to_sentence). Use facet_labels = ggplot2::label_value to turn off default sentence case transformation.

facet_na

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

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.

caption_wrap

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

font_family

Font family to use. Defaults to "".

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.
