Source: R/rub_plot.R
rub_plot_type_1.Rd

Vertical stacked bar chart in the RUB corporate design. The variables x_var, y_var and fill_var are required, all others are optional.

Usage

rub_plot_type_1(
  df,
  x_var,
  x_var_label = NULL,
  y_var,
  y_axis_label = "",
  fill_var,
  fill_reverse = FALSE,
  fill_label = NULL,
  caption = "",
  caption_prefix = "Quelle:",
  filter_cutoff = 0.04,
  facet_var = NULL,
  color = RUB_colors["blue"],
  palette_reverse = FALSE,
  base_family = get_font_df()[["family"]],
  base_size = 11,
  plot_width = 6.8
)

Arguments

df

Data frame

x_var

Required variable name for the variable containing the discrete x-coordinates.

x_var_label

Optional variable name for the character variable containing the names of the x variable, defaults to NULL.

y_var

Required variable name for the variable containing the y-coordinates. Will be coerced to numeric with as.numeric.

y_axis_label

Optional label for the y-axis, defaults to an empty string.

fill_var

Variable name for the discrete variable which determines the groups to be stacked, e.g. degree.

fill_reverse

Boolean indicating whether the order of the fill variable should be reversed, defaults to FALSE.

fill_label

Optional variable name for the character variable containing the names of the fill variable, defaults to NULL.

caption

Optional character containing the data source for the figure (prefix 'Quelle:' is automatically added).

caption_prefix

Optional character containing the prefix for the caption, defaults to 'Quelle:'.

filter_cutoff

Optional cutoff value for the suppression of data labels. By default, all values below 0.04 of the total value of the stacked bar chart are suppressed.

facet_var

Optional variable name for the discrete variable to facet by, defaults to NULL.

color

Color for font and borders, defaults to RUB_colors["blue"], i.e. #003560.

palette_reverse

Optional boolean indicating whether the colors in the palette should be reversed, defaults to FALSE.

base_family

base font family, defaults to RubFlama

base_size

base font size, defaults to 11

plot_width

Width of the plot in inches, defaults to 6.8

Value

A ggplot object

# x_var is mapped to term, y_var to students, and the fill_var to degree.
# base_size increases the text sizes from the default, 11, to 14. The font
# family is changed from "RubFlama" to "sans" (available on all systems).
