Arguments

data

A tibble or dataframe. Required input.

x_var

Unquoted variable to be on the x scale (i.e. character, factor, logical, numeric, date or datetime). If numeric, date or datetime, variable values are bins that are mutually exclusive and equidistant. Required input.

y_var

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

text_var

Unquoted variable to be used as a customised tooltip in combination with plotly::ggplotly(plot, tooltip = "text"). Defaults to NULL.

pal

Character vector of hex codes.

width

Width of bars. Defaults to 0.75.

alpha

The alpha of the fill. Defaults to 1.

size_line

The size of the outlines of bars.

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_na

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

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_reorder

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

x_rev

For a categorical 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

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 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_na

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

y_pretty_n

For a numeric or date y variable, the desired number of intervals on the y 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.

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.

mobile

Whether the plot is to be displayed on a mobile device. Defaults to FALSE. If within a shiny app with the mobileDetect function, then use mobile = input$isMobile.

Value

A ggplot object.
